Chinati Sheepmoth - Hemileuca chinatiensis

Hudspeth, Crockett, Culberson, Presidio, Brewster, Pecos, & Terrell Counties, Texas


Range: 

Trans-Pecos of West Texas, plus Crockett Co., 28:x:1991 per Chris Durden.

In October 1980, Bowman (1985) collected 25 examples just south of Whites City, Eddy Co., New Mexico of a darker phenotype appeared to be H. chinatiensis.

Not reported as likely for adjacent Mexico (Tuskes et al. 1996).

Flight Period: Adults occur from September into November, mostly in late October.

Flight Time: Mainly late-morning to mid-afternoon. (11AM to 3PM). 

Habitat: Occurs in shrubby desert areas.

Larval Host Plants: H. chinatiensis have a strong preference for flower buds over foliage. (Michael Van Buskirk, pers. comm)

Littleleaf Sumac - Rhus microphylla is the most commonly used foodplant - Tuske et al. (1996)

Larvae also feed on:

Mimosa lindheimeri, M. borealis, M. biuncifera - Family Fabaceae
Forestiera angustifolia
- Family Oleaceae
Ephedra nevadensis aspera
- Family Ephedraceae
Rhus aromatica flabelliformis
, R. microphylla - Family Anacardiaceae
Mahonia trifoliata
- Family Berberidaceae
Krameria parviflora -
Family Krameriaceae

Type Locality: Shafter, Chinati Mountains, Texas.

Conservation Status: Although limited in range, this species can be locally common some years.

Global Status: G3 - Vulnerable - NatureServe

Similar Species: 

The genus Hemileuca consists of 23 described species, 16 of which have partial or complete distributional patterns north of Mexico. (Tuskes, 1978).
