Identification

Det. M. A. Quinn, 2013

Differs from the similar D. glabrata in:
- larger eyes (frontal width between eyes less than half of heads' width);
- dark streak running down front between eyes
- last antennal segment pale.
Range
Hidalgo and Cameron Counties of southmost Texas / Mexico (Sinaloa). (1)
Season
Number of compiled Texas collecting events by month:
March (2), April (1), May (1), June (3), July (1), September (4), October (8). (2)
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)
Phaulothamnus distribution in TX - USDA Plants Database
Remarks
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)
Texas Parks and Wildlife considers this a SGCN (3)
