Explanation of Names

3 spp. in our area, ~150 total(1)
Large, boldly-marked net-winged beetles with broad, delicate elytra, flared out towards the rear.
Keys to spp. in(3)
(pl. XXV) and(4)
may not apply to all specimens
New World; in our area, eastern (NB-FL to MB-TX)(1)(5)
adults on flowers and vegetation, esp. near water(2)
C. reticulatum found on goldenrods, etc. in late summer, also in woodlands; C. discrepans and terminale are woodland species.
adults take nectar; larvae prey on small arthropods under bark, or perhaps slime molds, fungi and fermenting plant juices.
Eggs laid on bark of dead or injured trees. Larvae feed on insects under bark and pupate there.
Larvae found in rotten logs, under loose bark and, sometimes in soil or leaf litter, usually in groups.

Like other members of the Lycidae family, they contain a toxic compound, an acetylenic acid. They are rejected by thrushes, wolf spiders, and orb-weaving spiders. T. Eisner
