Hemileuca electra mojavensis
Tuskes & McElfresh, 1993
Hemileuca electra mojavensis is a of buck moth in the Saturniidae, first described by Tuskes & McElfresh in 1993. As a member of the Hemileucinae , its larvae bear venomous spines characteristic of this group. The subspecies is associated with the Mojave Desert region and exhibits geographic variation typical of the Hemileuca electra .

Identification
Distinguished from other Hemileuca electra by geographic distribution in the Mojave Desert region and associated morphological characteristics. The shows significant geographic variation in coloration and pattern. Specific diagnostic features for this subspecies require reference to the original description by Tuskes & McElfresh (1993).
Habitat
Associated with the Mojave Desert region of North America. Larval plants include oak (Quercus spp.) and other woody vegetation typical of desert and semi-arid environments.
Distribution
Recorded from Middle America and North America. Specifically associated with the Mojave Desert region of the southwestern United States.
Seasonality
fly during the day, typically in late summer and early autumn. The larval stage extends through spring and summer, with occurring in soil or leaf litter.
Diet
Larvae feed on oak leaves (Quercus spp.) and potentially other woody plants. do not feed; they rely on fat reserves accumulated during larval development.
Host Associations
- Quercus - larval oak
Life Cycle
Complete with four stages: , larva, pupa, and . Larvae are gregarious in early instars. occurs in soil or protected locations. Adults emerge, mate, and females deposit eggs on plants. Adults are short-lived, surviving only a few days.
Behavior
are (day-flying), unusual among Saturniidae. Larvae are gregarious, traveling and feeding in groups. Females emit -specific to attract males, which can detect these scents from considerable distances.
Ecological Role
Larvae function as herbivores on woody vegetation, contributing to nutrient cycling. serve as prey for birds, bats, and other . The is part of the diverse Hemileucinae fauna of North American deserts and semi-arid regions.
Human Relevance
Larvae pose a medical concern due to urticating spines that can cause painful stings, localized reactions, and potential effects in sensitive individuals. The is of interest to lepidopterists and naturalists. Like other buck moths, it contributes to the biodiversity of desert and may be affected by loss and light pollution.

Misconceptions
The 'buck moth' and related 'sheep moth' names for other Hemileuca have led to false assumptions that larvae feed on animal wool or hair. Larvae feed exclusively on plants. The stinging capability of larvae is sometimes underestimated due to the attractive appearance of the caterpillars.
More Details
Taxonomic history
Described as a new by Tuskes & McElfresh in 1993, reflecting recognition of geographic variation within the Hemileuca electra . The Hemileuca contains approximately 24 in North America, with ongoing taxonomic study using molecular methods.
Venom characteristics
The urticating spines contain venom that causes immediate pain described as burning or 'white hot,' with potential for localized swelling, redness, and blister formation. reactions can occur in sensitive individuals. Medical attention should be sought for severe reactions or contact with mucous .
