ABSTRACT: Adult mordellid beetles were monitored at
Brackenridge Field Laboratory in Austin, Texas from January 1990 through December 1990 using a Malaise trap.
A total of 754 specimens representing 35 species (17% of the North American fauna) and one subspecies were taken in this study. Twenty-eight of the species and one subspecies are recorded for the first time from Texas. Specimens were collected as early as March 13-19 and as late as November 27-December 3. Up to 19 species, nearly 10% of the mordellid fauna of North American north of Mexico, were collected in a single week. However, 19 (52%) of the taxa reported in this study were represented by five or fewer specimens indicating that most species were relatively rare. The seasonal flight pattern indicated a unimodal flight activity pattern for the family and also for most species.
