4 species listed on the Florida Checklist: https://www.freshfromflorida.com/Divisions-Offices/Plant-Industry/Florida-State-Collection-of-Arthropods/Explore-the-Collection/Insect-Collection/Coleoptera/Florida-Beetle-Checklist/Suborder-Polyphaga/Series-Scarabaeiformia/Superfamily-Scarabaeiformia/Scarabaeidae

“dung-rollers, apparently. Adults found on dung, and sometimes on carrion.
Keying species is rather difficult from photographs.”

CENTRAL FLORIDA CRITTER OF THE DAY: Clay-colored Leaf Beetle (Anomoea laticlavia)

Order Coleoptera – Beetles
Suborder Polyphaga – Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles
No Taxon Series Cucujiformia
Superfamily Chrysomeloidea – Long-horned and Leaf Beetles
Family Chrysomelidae – Leaf Beetles
Subfamily Cryptocephalinae – Case-bearing Leaf Beetles
Tribe Clytrini
Subtribe Clytrina

Feeds on a variety of forbs and shrubs: Lespedeza; Honey Locust, Gleditsia tricanthos; Willow, Salix; Oak, Quercus; Persimmon, Diospyros virginiana; Ragweed, Ambrosia.

larvae are myrmecophiles having an association with ants of the genus Formica.

Larva are connected with ants` nests. (leb.daba.lv/36-m1.pdf )

“The first of the three main study insects, Anomoea laticlavia (Forster), is a large (6-8 mm) yellow and black beetle (Chrysomelidae, Clytrinae), which consumes material from both immature inflorescences and young vegetative tissue. This beetle often feeds in one area of a raceme for several hours, creating a pit where many immature flowers are destroyed. Amorpha fruticosa L. (Fabaceae, false indigo) is the only other local plant on which I have observed A. laticlavia, but Dillon and Dillon (1961) report its presence on several other species, including Lespedeza spp. (Fabaceae, bush clover), Ambrosia spp.
(Asteraceae, ragweed), Ceanothus americanus L. (Rhamnaceae, Jersey tea), Gledistia triacanthos L. (Caesalpiniaceae, honey locust), and Salix spp. (Salicaceae, willow).”

CENTRAL FLORIDA CRITTER OF THE DAY: Long-horned Beetle (Eburia distincta)

Caught between the screen and the window glass, not sure how he managed that.

One of the boring coleoptera (lived up to that description ….not much of a conversationalist) 😉

“reared from cypress, but probably uses other hosts, too

CENTRAL FLORIDA CRITTER OF THE DAY: Spotless Lady Beetle larva (Cycloneda sanguinea)

This species of ladybug is native to Florida.
Diet: aphids. The larval stage may be even more beneficial than as adults since the larvae have voracious appetites. If you wash your aphids off your ornamental plants, you remove the food source for the beneficial so they will go elsewhere to reproduce. Be patient.

Keep in mind that Not all ladybugs without spots are native. Harmonia is an introduced species which can outcompete our natives, especially the species in the photo. (source: https://esa.confex.com/esa/2001/techprogram/paper_1422.htm)

If you buy ladybugs, check what species you are introducing. Many sold commercially are non-native species.
