I have taken this species in the Sabal Palm Grove Preserve on a few occasions, but only once was it abundant. On that date, I took both adults and larvae on from Phaulothamnus (Achatocarpaceae) (E. G. Riley, pers. obser.).
(Probably Snake-Eyes - Phaulothamnus spinescens)
Blake (1955) suspected that this species was not native to southern Texas but rather Sinaloa Mexico. The earliest year of collection in Texas is 1939. (2)
