(Arizona, California, Nevada, New
Mexico
, Oklahoma and Texas).
Activity.
Males were active from late spring through late summer (June through August).
Remarks.
Sphaeropthalma pallida
were distributed uniformly over sand dune and non-dune habitats (U=15.5, p>0.2). Forty-two
S. pallida
males were collected from June through August via light trapping. Seven
S. pallida
males were found at the NTS in August (
Ferguson 1967
).
