The natural history of Telegeusis texensis Fleenor and Taber is reviewed and summarized. Over 2,500 male specimens of this species have been reported from Malaise, flight intercept, and light traps in the decade following its description, making it the best known species of the family Telegeusidae. Nevertheless, larvae, larval and pupal microhabitats, and adult females remain undiscovered, and adult males are known only as trapping “artifacts.” Hence, only seasonal appearance, flight activity, and the geographic distribution of males have been documented. The paucity of life history biology about this species will likely be remedied only after adult males are detected elsewhere in the habitat than at man-made flight intercept barriers and traps.
