Season
Number of compiled Texas collecting events by month:
March (2), April (1), May (1), June (3), July (1), September (4), October (8). (3)
Food
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)
Remarks
The earliest year of collection in Texas is 1939. (3)
Texas considers this a SGCN (4)
