Overview of our faunaTaxa not yet in the guide are marked (*)
Family LYCIDAE
Subfamily Lycinae
Identification
Larvae have the head widened anteriorly, somewhat depressed; antennae short and robust, prominent, 2-segmented; and the abdomen largely 9-segmented. If a 10th segment is present, it is very small, hardly sclerotized, and not dorsally visible.
Range
worldwide and throughout NA; much more diverse in warmer climes(1)
Habitat
for many groups, typically woodlands
Food
Adults eat nectar and honeydew. Larvae: Despite anecdotal reports of carnivory, most, if not all, feed on myxomycetes or metabolic products of fungi(1)
Remarks
Many spp. aggregate in one of their life stages(1)
Many are unpalatable to predators due to ingesting toxic chemicals. They present aposematic colors that advertise their toxicity.(Chemoecology. Defensive Chemistry of Lycid Beetles and of Mimetic Cerambycid Beetles that Feed on Them)
Larvae of (Lampyridae) have the head elongate and subcylindrical, retractable antennae 3-segmented, and 10 abdominal segments present, the 10th concealed ventrally, the preceding segments thus often curved downward.
