CUTEREBRA TENEBROSA: DESCRIPTION OF IMMATURE STAGES AND A REDESCRIPTION OF THE ADULT (DIPTERA: CUTEREBRIDAE)

Abstract

AbstractImmature stages of the rodent bot fly, Cuterebra tenebrosa Coquillett, from central Washington are described and illustrated. Redescription of both sexes of the adult fly are also provided. Larval cuticular spines and posterior spiracular patterns are distinctive for second instars. Important characters of third instars include shape and number of points on cuticular spines and papillae arrangement. C. tenebrosa parasitizes bushy-tailed wood rats (Neotoma cinerea) and desert wood rats (N. lepida) in the western United States and western Canada.
