Lycids of the genus Lycus have fronts elongated into beaks (White, 1983)
There were large numbers of these feeding on the tiny blossoms of Aloysia wrightii (Oreganillo)
County Record Data from E.G. Riley, Sept. 2006
Range: Arizona to Texas, south to Mexico (Blackwelder, 1944-57)
Despite anecdotal accounts that larvae are carnivores, probably most, if not all, feed on myxomycetes or metabolic products of fungi (Lawrence 1982). Lycus larvae may be seen moving over open ground in the early evening. Adult lycids eat nectar and honeydew. Numerous species aggregate in one or their life stages (Eisner & Kafatos 1962). Both larvae and adults are distasteful and are often aposematically colored.
Similar Species: There are 11 species of Lycus north of Mexico from Arizona, Colorado, New Mexico and Texas (Arnett et al, 2002).
Lycus fernandezi Dugés
Lycus sanguineus (Gorham)
Lycus simulans (Schaeffer)
