The objectives of the present study were to determine the Hlppelates species in Central California, to study the geographic and seasonal distribution of the species, and to evaluate their relative medical importance. The investigations were conducted in parts of Mariposa, Merced, Fresno, Kings, Tulare, and Kern Counties. The principal means of acquiring information were through the use of stationary and mobile bait traps and the hand aspirator.
