Walking Iris

The blooms of Walking Iris can take you by surprise. Unlike other plants that send up obvious flower stalks and bloom heads that slowly emerge, Walking Iris flowers suddenly appear one day on what just seems to be another leaf of the plant. They bloom for a short time, usually less than a day, but they flowers are spectacular while they last. Here at BioWorks, we have yellow Walking Iris, known botanically as Neomarica longifolia.

DSCN0173
Though not a true iris, this plant is a member of the same family, Iridaceae. The name Neomarica comes from the Greek “neo” meaning “new”, and “Marica”, a Roman nymph said to be the goddess of the swamp and the mother of Faunus, god of the forest. The common name Walking Iris is due to the unique way the plant propagates itself. After the flower is pollinated and dies back, a new plantlet emerges at that site. As it grows heavier, it bends the stalk over to the ground, where it takes root and begins a new plant. This makes Walking Iris very easy to divide and spread around your garden or share with friends.

DSCN0174

Grow Walking Iris in almost any light exposure, from full sun to full shade. It likes well-drained soil but does best when watered regularly. Native to Central and South America, it’s hardy to zone 9 but must be brought inside for the winter in colder regions. New plants may flower the first year, or may take up to two years to produce blooms.

How to ID Your Bug

Question Mark butterfly pic sent in for ID by Patty Wilson
We get lots of requests here from people who would like help identifying a  caterpillar, moth or butterfly that they have found. We honestly don’t know everything or even a large portion of everything there is to know about lepidoptera, but we have learned some handy tricks for identification.
First if you are looking at a moth or butterfly then determine which you are looking at. We posted a guide a while ago about how to identify the differences between moths and butterflies. Go through the checklist and find out what sort of creature you are dealing with.
Here are some great sites that help us to identify butterflies and moths in North America:
If you are totally lost then you can try submitting an image of your bug to these sites
  • Bug Guide ID Request page allows you to post and image of your insect after White banded sphinx larva brought in by a MOSI guest you have created an account and logged in.
  • What’s That Bug allows you to mail in an image of your insect to the folks that run the website and they will have a go at identifying it for you.
  • Project Noah is a social networking site that lets you upload wildlife images via your computer or a smart phone application. Just click the box that reads “Help me ID this species” and perhaps someone in the friendly Project Noah community might have an answer for you.
If you want to have some good books on hand, we can recommend the following books as helpful identification guides. The sources listed here mostly pertain to Florida or the eastern portion of North America.

Autumn Butterflies

In the Fall we start to see different species of butterflies in greater numbers than in summer and some species will seem to completely disappear. Here is a quick guide to some of the common autumn butterfly species for west central Florida and the plants that help attract them to an autumn garden.
Butterfly gardens need to be planted with both host plants and nectar plants to best serve the needs of your butterfly population. Having nectar plants means you have a butterfly garden. Adding host plants almost guarantees you a butterfly factory.

Butterflies of Autumn and their Larval Plants
DSCN0386 
The Milkweed Butterflies: Monarch and Queens are just as common in the fall as in summer and sometimes fare better with the slightly lower temperatures. Monarchs and Queens both host on milkweeds. Scarlet Milkweed (Asclepias curassavica) is the most common commercial milkweed to be found in stores and both species will host on it. Aphids can be a problem on milkweeds but instead of using a pesticide, try using your hose nozzle at close range to knock the aphids loose.

Monarch caterpillars have fleshy antenna-like tubercles at both ends of their bodies and Queen larvae have three sets of tubercles, one at each end and an extra pair near their head end. You’ll also notice that Queens eat slower than Monarchs who are defiantly the dining champs among the butterflies.Gulf Fritillary butterflies mating

The Heliconians: Zebra Longwings and Gulf Fritillary are both abundant during  Autumn in the Tampa Bay Region. Gulf Fritillary butterflies begin to migrate southward during the Autumn months and become even more common in West Central Florida.

Plant passionvine (Passiflora) to attract these species to lay eggs in your garden. I recommend planting at least two plants, one in the sun and one in the shade. Zebra Longwings tend to prefer shaded plants for egg-laying. Avoid red passionvines as their glossy leaves are inedible to these caterpillars and stick with passionvine that have purple or purple and white flowers. Maypop (Passiflora incarnata) is a Florida native variety that is much beloved of these species.

Orange Barred Sulphur The Sulphurs: Orange Barred Sulphurs, Cloudless Sulphurs and Sleepy Oranges are just a few of the common Autumn sulphur species.

These species all host on various plants in the cassia family. In the Fall when these plants flower with bright yellow blossoms, caterpillars that eat the flowers turn yellow instead of their usual green color! Winter Cassia (Cassia bicapsularis) can become a very large shrub, so plant it in a place it can spread or be prepared for pruning. However, the blooms on cassia make it worth the effort every year.

The Whites: There are several species ofDSCN0234 white butterfly that can be found in the  Autumn such as the Cabbage White, Checkered White and Great Florida White. These species host on greens in the mustard family like cabbages, mustard greens and collard greens. Try picking up a few of these greens not for food but for the butterflies.

These butterflies can often be seen on roadsides and medians throughout Florida and host on a common weed called Peppergrass (Lepidium virginicum) or Poor Man’s Pepper that you may already have growing in your yard. If you have a fenced yard that your neighbors won’t complain about, consider letting a small patch of peppergrass go wild by mowing around it. It is amazing how many butterflies are drawn to common weeds.

DSCN0287 Black Swallowtails: Black swallowtails begin to decline in the autumn but you can still find them through November and early December. Plant parsley, fennel or dill to attract them to lay eggs. Their eggs are tiny whitish globes that will often be found on the freshest growth of the hosts.

When you buy plants from a nursery, even kitchen herbs, they have likely been treated with a biological insecticide which will render them inedible to caterpillars for a few weeks. If you have a green thumb, try growing some parsley or dill from seed to ensure that it will be pesticide free.

DSCN0389
 Polydamas Swallowtails: Polydamas Swallowtails will continue right through  Autumn and into Winter and will be found so long as we don’t have a hard freeze. These caterpillars are voracious eaters that host on pipevines (Aristolochia).

Pretty much any species of pipevine will satisfy their hunger and you’ll likely find clusters of golden yellow eggs in no time. Pipevines are in a vine and will need somewhere to grow but they are a great cover on a chain link fence and also work well on arbors or trellises. The flowers are really neat too.

Giant Swallowtail Giant Swallowtail: Giants can still be found throughout the Fall. They host on a variety of Citrus like lemon and sour orange and also on Wild Lime (Zanthoxylum fagara) and Hercules Club (Zanthoxylum clava-herculis) , two Florida native trees that can be tricky to find. Both trees have spines so care should be taken when working around them. Giant Swallowtail eggs are orange spheres and their caterpillars look like shiny bird poop.

Skippers: Skipper butterflies of the Fiery Skipperfamily Hesperidae come in lots of shapes  and sizes. In general they tend to be smaller butterflies who are quick in flight and tend to be somewhat dull in color. Throughout the summer and fall, many species of Skippers are numerous in Tampa Bay. Although many people confuse these tiny creatures with moths, they are indeed butterflies.

Especially look for the Long Tailed Skipper and Fiery Skipper. You can lure Long Tailed Skippers to your yard by planting beans so the adults will lay eggs. Fiery Skippers can often be seen at clusters of small flowers like lantana and salvia.

Autumn Nectar Plants

Firebush flowers Try these Florida native Autumn nectar plants: Aster, Beach Sunflower, Black-Eyed Susan, Blazing Star, Blue Porterweed, Dalea, Firebush, Florida Paintbrush, Garberia, Goldenrod, Hibiscus, Lantana, Lobelia, Milkweed, Mistflower, Phlox, Sage, Spanish Needles, Stoke’s Aster, Sunflower, Tick-seed, Verbena
Try these non-native options for nectar plants: Buddliea, Golden Dewdrop, Heliotrope, Marigolds, Mexican Flamevine, Moss Verbena, Penta,

Some are easier to find than others, but take that list with you to the nursery and see what you can come up with. Some nurseries specialize in Florida native plant species and these are often preferred by butterflies. Ask at your nursery for recommendations because if it is blooming this season, chances are butterflies might enjoy it. Also, make sure to watch for which plants are drawing butterflies at your nursery. Those are sure to be winners.

Mexican Sage

It’s no secret we’re a big fan of salvia here at the Butterfly Garden. With the exception of Salvia splendens, this genus of plants offers fantastic nectar sources for butterflies. Salvia leucantha, also known as Mexican Sage, is a late-season bloomer that fills the garden with purple blooms that bring butterflies and pollinators like bees in droves.

DSCN0134
Native to Central American and Mexico, Mexican Sage has silvery green foliage that grows into almost shrub-like proportions by the end of summer (3 feet high and tall), when the flower stalks emerge and add another foot or so to the height. The stalks and calyxes are purple and fuzzy, while the blooms themselves are a soft white color.

DSCN0138

As you might expect from a plant native to more tropical climates, Mexican Sage is frost-sensitive, and is generally killed back to the ground in a hard freeze. Fortunately, it returns quickly from the base, putting on lush silvery growth all spring and summer until the blooms emerge in the late summer/early fall. The blooms continue until a killing frost. It’s drought-tolerant and prefers full sun to grow best. You can usually find Mexican Sage for sale starting in late summer at most plant nurseries, making it an easy and excellent addition to the southern butterfly garden.

A corner of the gardens

DSCN0252 A good lunch is made better by a beautiful place to eat. So many museum staff and guests use this one particular picnic table beneath the spreading bows of a huge double trunked live oak that we like to make this area special. With the ‘nice weather’ season about to start, we decided to work on this area as our prelude to the rest of the Historic Tree Grove end of summer tasks.

On Friday we added border of coral colored impatiens along with some blue daze, indigo spires salvia and a few donated pink begonias. These all mix in nicely with the bedding plants that include flax lily, African iris, ferns, gingers, coleus and artemisia.

DSCN0007 The last addition for the day was a frilly species of hibiscus commonly known as Japanese lantern (Hibiscus schizopetalus). This quirkily botanical-named hibiscus is still young but produces gorgeous and unlikely looking blooms.

The picnic area can be found beneath the Dr. Richard T. Bowers Sand Live Oak in the Historic Tree Grove at MOSI. Next time you visit the museum we invite you to bring your lunch outside and watch the butterflies play.

We’ll be doing lots of work in the outside gardens for the next few weeks. Please feel free to ask us your questions or tell us what you like about the gardens.

Green Leaves: Selecting Good Host Plants for Caterpillars

Buckeye butterfly eggs on plantagoCaterpillars of butterflies are specialists when it comes to eating. Each species is generally limited to one type of host plant or maybe even a small family of plants. For instance, caterpillars of the Monarch butterfly eat milkweed. The type of milkweed may vary based upon where the caterpillar is located and what sort of milkweed grows there  but you can bet that if you find a monarch caterpillar, it will be on a milkweed plant.

 Good host plants for caterpillars have to be more than what the caterpillar can possibly eat. You must also consider which species of a host plant will do best in your yard. A northern species of milkweed is sure to attract Monarchs in Pennsylvania, but if planted here the plant with be overwhelmed by the heat and even rains of a Florida summer. You must look for a species that will thrive in your Seeds of Virginia Snakerootyard.

Buying seeds and bare root plants online can be a great way to save money on  butterfly gardening, but make sure to research that the seeds you are planting will grow well here. Take a look at the Plant Files section of the Dave’s Garden website. There you can search for plants by name and read reviews by other readers all over the country. These other gardeners will note how the plant is growing in their local area and may help to give you some clues on how a species might do in your garden.

One last important factor to consider is that plants purchased for the butterfly garden should be pesticide free. Ask a lot of questions about the use of pesticides Polydamas Swallowtail caterpillar when you purchase plants, especially if you intend to feed them to caterpillars right away. Some plants listed as pesticide free will still be toxic to caterpillars. Biological pesticides like bacteria that harm insects but not humans are commonly employed to keep nursery plants looking healthy. If you can, quarantine new plants for 2-3 weeks before you expect caterpillars to eat the leaves and water and wash the leaves of the new plants often.

Sweet Nectar: Selecting Good Nectar Plants for your Butterfly Garden

Julia Longwing and Monarch on Anise Hyssop To attract butterflies to your yard you will need nectar. Nectar is a sugary water substance found inside of many flowers and is a mainstay for butterflies. Butterflies extend their proboscis and insert it into flowers to drink the nectar found within. Nectar is mainly sugar and contains very few nutrients. Butterflies subsisting upon nectar have fairly short life spans usually about 2 to 4 weeks.
Not all plants produce good amounts of nectar so just planting a bush with flowers in your yard may not bring the butterflies that you seek. Here are some tips for choosing good nectar plants for your garden.

 Butterflies like choice: By providing lots of different flower options you can attract more species and greater numbers of butterflies. Plants of differing heights, Bidens 3various colors and with long bloom seasons can make your garden more attractive to butterflies.

Sometimes a weed is not a weed. Try leaving a small section of backyard to go wild  and find out what wildflowers are already growing in your garden. Some of these flowers, like Spanish needles may not be the most attractive to us but butterflies enjoy them a great deal.

A riot of color: Butterflies can perceive color and some species are drawn to particular colors. Planting multiple species of flowers that bloom in an array of colors will help to attract more species of butterflies. DSCN0003

Size Matters: Butterflies come in all sorts of sizes and will need flowers that range in size from tiny to fairly large. Little butterflies can often be found at tiny flowers while larger butterflies often select flowers that are larger and contain more nectar. Tiny flowers of the scorpion tail will draw little blue butterflies and diminutive hairstreaks while the larger blooms of firebush attract swallowtails and sulphurs.

Clusters: Butterflies are often drawn to flowers that grow in clusters. These provide more nectar in a small area and Gold Mound Lantanaallow butterflies to feed without having to do a lot of work. Milkweeds, salvia, firebush, pentas and lantana all provide clusters of flowers that make speed eating easy for butterflies.

Shop smart and research: While wandering around a plant nursery, pay attention to what the local butterflies are using for nectar there. Each time I shop I make sure to check out the plant species that have the most butterfly attention and then use my smart phone to learn more about the plants if I am not familiar with the species. This helps me make sure that the delicious nectar plants will thrive in the conditions already present in my yard or in the MOSI gardens. When looking at new plants, try some research on the front end. A simple web-search on a particular plant will probably let you know if it is attractive to butterflies.DSCN0098

Florida Friendly: Make sure to buy plants that will do well in your garden’s sun, soil and water conditions and check out this list of Florida native nectar plants that attract butterflies. Some native plants can be hard to find but many are worth the effort.

Seasonal changes: Each season should see different plants blooming in your gardens just as each season brings lows or highs for various butterfly populations. If all of your nectar plants bloom in the spring, your garden may not attract butterflies in the summer, fall or winter. Try to pick an array of nectar plants that will provide year-round nectar.

BEWARE! Flannel Moth Caterpillar

Guests frequently drop by BioWorks with “mystery bugs” for us to identify. Not too long ago, I answered a knock at the lab door and found a boy and his mom, holding this caterpillar and looking for an ID.

DSCN0116 
My immediate thought was: “DON’T PANIC. You don’t want to scare this boy and his mom!” You see, I was pretty sure that the fuzzy little caterpillar he was holding so precariously on a small jar lid was in fact one of the most toxic caterpillars out there – the Flannel Moth Caterpillar (Megalopyge opercularis), also sometimes called the Puss Moth or Puss Caterpillar. Lurking in those hairs covering the body are spines that inject venom upon the slightest touch.

DSCN0122 The first symptom of a Flannel Moth caterpillar sting is most frequently described as “searing pain”. The pain radiates up from the sting site and can cause nausea, swelling, vomiting, chest pains, and other horrifying-sounding symptoms. In severe cases, the victim may begin to experience difficulty breathing and will need to seek immediate medical attention. There’s no antidote for this sting – the only thing you can really do is apply appropriate first aid and wait it out.

Risk-takers that we are, we decided to keep this caterpillar in a tank in the lab and try to raise it to adulthood, as the adult moth is very unusual and completely harmless. We are feeding it live oak, the most common host plant, and handling it only when absolutely necessary, wearing gloves and taking all possible precautions.

DSCN0121 A face only a mother could love?

Children are often the victims of this caterpillar, since it looks so soft and inviting to pet. Other toxic caterpillars, like Io Moths and Saddlebacks, are just as toxic but their bright colors provide better warning. We’re relieved that the local boy who found this creature wasn’t stung. He was very lucky, since even the slightest contact is said to cause extreme pain. Fortunately, now he’ll know what to look out for, and so will you.

What’s Flying? – October

October came in on a breath of fresh air, as the first weekend of the month brought the first cool front to Tampa. With the approach of cooler weather and changes to some of the blooms in the gardens, butterfly habits and appearances will start to change, This month brought several species we hadn’t seen in awhile, including an Eastern Tiger Swallowtail and several Viceroys.  Here are the species we’ve been seeing in the gardens recently:

Notes from the Field:

  • Eastern Black SwallowtailSince the extremely cold winter of 2010, White Peacock butterflies have been scarce in the gardens. In the last month or so, we’ve seen a big uptick in their numbers, and just last week we were pleased to find larva on the water hyssop in the small pond. More than 20 small caterpillars are being raised in the lab now, and should be making their appearance as butterflies in the Flight Enclosure in the weeks ahead.
  • A new sighting in the last few weeks was an Eastern Tiger Swallowtail, a female in beautiful condition. While northern gardens are filled with these large butterflies in the summer, they seem to be a little more rare down south. The cooler weather will likely bring more to the area in weeks ahead.
  • Hummingbirds are occasional visitors to the garden. A female was seen several days in a row recently, feeding on firebush behind the Flight Enclosure. We haven’t seen her since, so she may have been passing through as she migrated south for the winter.
  • After a slow start to the season, Polydamas butterflies are now abundant and laying hundreds of eggs each week on our Pipevines.
