Explanation of Names
Tetraopes mandibularis Chemsak 1963
Range
TX-OK (w. OK and panhandle region of TX) (1)(2)(3)
Type Locality: Childress, Childress Co., Texas; Collected by J. Mitchell, 1906
Habitat
asso. w/ Asclepias latifolia in the Llano Estacado region of northwestern Texas and adjacent Oklahoma (1)(2)
Season
Jun-Aug (1)(Chemsak 1963)
Food
Host: Broadleaf Milkweed - Asclepias latifolia (1)(2)(4)
Remarks
This uncommonly encountered milkweed beetle is found in western Oklahoma and the panhandle region of Texas.
Forty-nine individuals were found in association with T. femoratus LeConte on Asclepias latifolia in Texas: Dickens Co., Double Rafter Ranch, 30-VII/29-VIII-79, 2/8-VII-80, [Marlin E. Rice]. Chemsak (1963) indicated that when a single host is utilized among two sympatric milkweed beetle species, one species is usually much less numerous than the other, and during a two year period, ca. 200 A. latifolia growing in a fallow field, yielded fewer T. mandibularis than T. femoratus, with the ratio being 1:3.2.
