Tegeticula mojavellaOlle Pellmyr
Wing expanse 19-24.5 mm. Forewing cream colored, hindwing light brownish gray and a distinctly darker outer section. Male genitalia with aedeagus 1.5-1.8 mm long, 0.030-0.035 mm in cross section; female genitalia with posterior apophyses 6.7-7.0 mm long, corpus bursae with signa 0.55-0.70 mm in diameter.
More cream colored than other species in the complex, yet similar, but readily distinguished from other members of the complex based on genitalic characters. A diagnostic key is provided.
The species is known from the fleshy-fruited yucca Y. schidigera. Females oviposit into flowers (Pellmyr 1999). Eggs are laid inside the ovary, between the wall and the ovules, generally in the upper portion.The larva feeds on developing seeds. Pupation occurs in a cocoon in the soil.
Most of the Mojave desert, from southern Nevada and desert portions in California south to the U.S.-Mexico border.
