No habitat associations other than general habitat of genus (see Exetastes genus page).

Specimens have been collected from April to July, with most being from May (Townes & Townes 1978).

Head and antennae black. Thorax almost entirely black, except for reddish-brown mesoscutum and pronotal collar,and yellowish scutellum. Front and middle legs entirely reddish-brown. Hind legs with femur and most of tibia reddish-brown, apex of tibia and first tarsal segment dark-brown to black, tarsi 2-4 white and tarsus 5 light brown. Gaster entirely reddish-brown. This subspecies is distinguishable from E. a. albitarsis by the lack of a white band in the antennae. It is distinguishable from the remaining two subspecies (E. a. concavus and E. a. arizonicus) by the reddish mesoscutum and and mid- and hind-coxae at least partly reddish (Townes & Townes 1978).

life history
Specific information not known. See Exetastes genus page for general life history.

No information available.

diet info
No host records. Host is probably Lepidoptera: Noctuidae.

This subspecies has been collected from southern British Columbia and Alberta to central California and Colorado (Townes & Townes 1978).

The single specimen in the Strickland Museum has the mesoscutum almost entirely reddish-brown, however the coxae are completely black. The subspecies of E. albitarsis are closely allied; this specimen may be an intermediate between E. a. crassisculptus and E. a. concavus, on the basis of the reddish-brown hind femur. Exetastes a. arizonicus has the hind femur black, and is only recorded from Arizona (Townes & Townes 1978)
