Coleoptera (Beetles)

CENTRAL FLORIDA CRITTER OF THE DAY: Darkling Beetle (Bothrotes canaliculatus acutus)

Darkling Beetles, as scavengers, are usually found in dark locations such as under debris, logs or stones.  They are members of the Tenebrionidae Family.

I arrived at the subspecies given the metallic luster based on this key: http://entnemdept.ufl.edu/teneb/subfamily_Pimeliinae.pdf

A study indicated the genus may feed on moth larvae:

“Species found preying on Mocis larvae were a Tenebrionid, Bothrotes fortis…”

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).”
