Spring Fishfly (Chauliodes rastricornis)

CENTRAL FLORIDA CRITTER OF THE DAY: Spring Fishfly (Chauliodes rastricornis)


Serrate Antennae is an identifying characteristic of females of the species. Males have pectinate (comb-like) antenna. So this is a guy.

Larvae aquatic, omnivorous(1); adults may not feed, though have been reported coming to moth “sugar” which this guy proves since I noticed him at night alongside all the moths dirtying up my window trying to get to my kitchen light.
