National Moth Week: Hummingbird Moth (Hemaris thysbe)


Adult Hummingbird Moth (Hemaris thysbe) © Laura Bennett-Kimble
On a springtime hike at Little Big Econ State Forest (Seminole County, Central Florida), my companions and I spotted a hummingbird moth working its way from thistle plant to thistle plant. I clicked my camera’s shutter button while standing as still as possible. The morning light was perfect, and the moth was not shy. It ended up next to me on a tall thistle, and the above image is one of the resulting photos.

The hummingbird moth—along with the similarly named hummingbird hawk moth that lacks transparent wing spots—is a member of the sphinx moth family (Sphingidae), which also includes the Pluto Sphinx moth. These creatures resemble hummingbirds in both their shapes and movement as they hover while sipping nectar from blossoms. The beating of their wings can even make a humming noise, similar to that of the birds.

You can attract the moths to your neighborhood with both nectar and larval host plants. These plump moths seek out host plants such as honeysuckle, snowberry, hawthorns, cherries and plums for their larvae. And in addition to thistle blooms, nectar sources for the adult moths include various native plants, such as beebalm, blueberry, and rockland lantana (Lantana depressa var. depressa).

Lantana, as you likely know, comes in both native and invasive varieties, so be careful what you plant. The Category 1 invasive Lantana strigocamara is considered one of the “Invasive exotics that are altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives,” according to the Florida Exotic Pest Plant Council. The Society recommends only planting Rockland Lantanta, Lantana depressa var depressa, Wild Lantana, Lantana involucrata, and Hammock Shrub Verbena, Lantana canescens from a reputable native nursery[1].

The hummingbird moth, which has a wingspan of up to just over 3 inches, is a wide-ranging species, with verified sightings from Alaska and the Northwest Territories east to Maine and Newfoundland and south to Florida and Texas.

The 8th annual National Moth Week is quickly coming to a close, but you can still participate in a citizen science project through iNaturalist and contribute to the body of knowledge about moths that have lifecycle relationships with Florida’s native plants.

Wednesday's Wildflower:Spanish Needle

Image
Spanish Needle, Bidens Alba Submitted by Donna Bollenbach, Suncoast Chapter Biden's alba , all photos by Donna Bollenbach Nothing attracts more butterflies and bees than a simple white flower called Bidens alba . Also called Romerillo, Beggar’s Tick, Spanish Needle or Monkey’s Lice, this Florida native wildflower is the third most reliable source of nectar for pollinators in our state. There would be many starving bees and butterflies if not for the Bidens family of flowers. More so, Bidens alba and its sister plant, Bidens pilosa , are both edible and have medicinal value. Yet, many gardeners have a love/hate relationship the plant, and some even consider it a pesky weed. Why?

Australian Pine: One of Florida's Least Wanted

Image
 Austrailian Pine fruits Australian pines seem to be everywhere in the coastal regions in the bottom half of Florida. Their name is deceiving because, while they are native to Australia, they aren't pines or even conifers. They are flowering trees with separate male and female flowers, and what look like needles are really green twiglets with close-set circles of tiny leaves that drop at the first sign of a drought. In the photo to the right, the light-colored lines are where leaves where once attached. Most of the photosynthesis takes place in the twiglets. There are three species of Australian pine ( Casuarina spp ) that have been imported into Florida for various purposes. They were widely planted to soak up the "swamps" in Florida, stabilize canals, and hold beaches. Unfortunately for Florida's ecosystems, the "pines" accomplished all this and more--like seeding prolifically, growing five feet or more per year, producing dense shade, and emitting

Tropical Milkweed is Harmful to Monarchs & Florida Ecosystems

Image
By Lilly Anderson-Messec The red and yellow blooms of tropical milkweed, Asclepias curassavica , are ubiquitous in Florida butterfly gardens. This non-native milkweed has exploded in popularity as demand for milkweed grows to support declining monarch butterfly populations. This tropical species is native to Mexico and very easy to propagate, so growers are able to quickly produce plant material to meet the milkweed demand. It’s also very showy, blooming prolifically all season and regrowing quickly after being decimated by hungry caterpillars.  Unfortunately, tropical milkweed has been an increasingly invasive species in Central and South Florida for many years, and has begun spreading in North Florida as well. It’s fast growth and prolific re-seeding have resulted in large monocultures of tropical milkweed in natural areas. This unchecked growth replaces native plants and disrupts the native ecosystems that both wildlife and humans rely on. The invasive quality of this plant is is j
