Effect of Systemic Use for Commercial Nursery Propagation of Asclepias currasavica on Monarch Larvae

People who buy milkweed plants (most commonly Tropical milkweed [Asclepias curassavica]) from big box stores such as Lowes and Home Depot to feed monarch larvae frequently report that their larvae often die after feeding on the purchased plants. This is likely due to the plants being treated with topical or systemic insecticides. However, detailed information concerning the exact chemicals used and their potential impact on monarch larval mortality is poorly understood. This study sought to provide information on insecticides and larval mortality.

Green antelopehorn, Asclepias viridis

Flower Friday: Green antelopehorn

Flower Friday

Green antelopehorn (Asclepias viridis) is an herbaceous perennial wildflower found in pinelands, pine rocklands and disturbed areas in a few Florida counties. It flowers winter through summer, with peak blooms in spring. Like many members of the milkweed family, Green antelopehorn is a larval host plant for Monarch, Queen and Soldier butterflies. Their caterpillars have adapted to feed on the plant, which contains a milky latex that is toxic to most animals. The flowers are also an important nectar source for bees and wasps.

Clasping warea, Warea amplexifolia

Jan. 25 Warea Tract Service Day

Events, News, Wildflower tag

Join us on our Jan. 25 service project as we visit and help protect Seminole State Forest’s Warea Tract. We will be removing invasive Natal grass and learning about the importance of the tract from Forester Mike Martin and Todd Angel. The Warea Tract holds many threatened and endangered species we may have the opportunity to see, including Florida bonamia (Bonamia grandiflora), Lewton’s polygala (Polygala lewtonii), Sweet-scented pigeonwings (Clitoria fragrans), Scrub plum (prunus geniculata) and Scrub buckwheat (Eriogonum longifolium var. gnaphalifolium).

Silver-spotted skipper

Know your native pollinators: Silver-spotted skipper

News, Pollinators

You might find one of these creatures hanging upside-down, but it’s not a bat (or a vampire). It’s a Silver-spotted skipper!

The Silver-spotted skipper is one of the largest, most widespread and recognizable skippers. It has a quick jerky flight that is typical of skippers. This type of butterfly is common and can be found from northern Mexico to southern Canada, as well as most of the continental United States.You can find Silver-spotted skippers throughout Florida. These butterflies enjoy a disturbed habitat, open woods, foothills, stream sides, prairie waterways, edges of forests, swamps, brushy areas and other open areas with nectar plants.

Carolina milkweed, Asclepias cinerea

Flower Friday: Carolina milkweed

Flower Friday

With its narrow leaves and fine stems, Carolina milkweed (Asclepias cinerea) can get lost among the wiregrass with which it typically grows. But its splendidly stellar blooms will stop you in your tracks. You’ll find it flowering in summer in sandhills, pine flatwoods and bogs throughout the Panhandle and North Florida. Like all members of the Asclepias genus, Carolina milkweed is a larval host plant for Monarch and Queen butterflies. Its flowers are an important nectar source for bees and wasps.

Gulf fritillary on Elliott's aster, Symphyotrichum elliottii

Know your native pollinators: Gulf fritillary

News, Pollinators

The Gulf fritillary is sometimes known as the Passion butterfly — so named because of its ardor for Passionflower. You will find so much to love about this unique pollinator!

Gulf fritillaries are medium-sized butterflies with elongated forewings that live in the extreme southern United States. Outside of the U.S., they are a broad-ranging species, found throughout Mexico, Central America, the Caribbean and into South America.Gulf fritillaries enjoy a variety of habitat including sunny roadsides, disturbed areas, edges, fields, pastures, woodlands, second-growth semitropical forests and urban areas like parks and yards.

Milkweed workday at St. Marks National Wildlife Refuge

News, Panhandle

U.S. Fish and Wildlife Service Ranger Scott Davis has been working on the milkweed restoration initiative since 2015, when he started with a single greenhouse table of seedlings. Since then he has been scouring the state for native milkweed populations and bringing seeds back to the refuge to propagate. He estimates that 300,000 plants have been grown there, which have been planted as part of restoration projects at state parks, state forests and national wildlife refuges across the state. It is no easy task to grow these plants, either.

Oak hairstreak butterfly, Satyrium favonius

Know your native pollinators: Oak hairstreak butterfly

News, Pollinators

You might not see very much of the Oak hairstreak butterfly, but that doesn’t mean they aren’t around. They are usually just hanging out in the trees above your head!

Oak hairstreak butterflies prefer the tree canopies of oak woodlands, wooded coastal areas, and oak hammocks. You can find them throughout much of the eastern United States, stretching as far west as New Mexico. They can be identified by the two tails on each hindwing, and have greyish-brown undersides with a blue tail-spot and orange coloring above.
