Crane flies belong to one of the most specious families of flies. The adult flies, also known as “mosquito hawks”, are not giant mosquitoes and do not bite, and though the name suggests it, they do not feed on mosquitoes. In general, the larvae are associated with aquatic and semi-aquatic habitats. The majority of crane flies are not pests.

Colletes stehpani Timberlake is thought to be a narrow oligolege of creosote bush, Larrea tridentata (DC.) Coville (Zygophyllaceae) with limited distribution in the Sonoran desert of the Western United States. Based on appraisal of a museum specimens and fieldsurveys from 1999 to 2001 on 21 sand dunes, we foundd C. stephani to be a much more widely distributed psammophile of theSonoran, Mojave, and Great Basin Deserts that utilizes two unrelated plant pollen scources,Larrea Cav. and Psorothamnus Rydb. (Fabaceae). The geologic history of the region suggests a potential host shift from the more ancient occupant, Psorothamnus, to the Neogene colonizer, Larrea.

Walnut husk fly (Order Diptera, Family Tephritidae; Fig. 1) is the most common insect pest of walnuts in Utah. Husk fly larvae (maggots) tunnel in walnut husks, causing them to soften and decay, and stain the shell (Fig. 2). Damaged husks are difficult to remove. If husk fly infestation occurs early in kernel development, nuts may shrivel, darken, become moldy, and drop from the tree (Fig. 3).
