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: 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.

CENTRAL FLORIDA CRITTER OF THE DAY: Tumbling Flower Beetle (Mordella knulli)

endemic to Florida (http://www.fsca-dpi.org/Coleoptera/Mike/mordell.htm)

Suborder Polyphaga (Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles)
No Taxon (Series Cucujiformia)
Superfamily Tenebrionoidea (Fungus, Bark, Darkling and Blister Beetles)
Family Mordellidae (Tumbling Flower Beetles)
Tribe Mordellini

“Larvae are believed to eat plant material in decaying wood, etc. Some are leaf and stem miners. Some are predaceous. Adults visit flowers.”
Learn: http://bugguide.net/node/view/144

Per Texas A&M Entomology Dept.:

“Tumbling flower beetles can be very abundant on flowers especially those in the carrot family (Umbellifera) and aster family (Compositae). The larvae feed in stems and dead wood. The pointed tip of the abdomen gives the family a second common name, the spinetailed beetles.”
