Explanation of Names
Pachyschelus fisheri Vogt, 1949a
Patronym for W. S. Fisher, of the Bureau of Entomology, United States Department of Agriculture.
9 spp. n. of Mex. (1)
Length is 2.6-3.0 mm,
the greatest width is 1.7 mm at base of pronotum. (2)
"This is a distinct buprestid beetle, not likely to be confused with similar species. ... The body is flattened and broadly wedge-shaped. The head and pronotum are copper-colored, the later with a narrow vague band of pubescence on each side at base. The scutellum and elytra are bright metallic blue, the latter with a distinct band of pubescence at apical third. The scutellum is large and triangular (as is typical of the genus)." (2)
apparently known from a single locality in southwestern Cameron County, Texas - Map (3)
3 mi. E Santa Maria, Cameron County, Texas. (2)
Number of compiled Texas collecting events by month:
June (1), July (1), August (2), September (2). Not collected since 1947. (2)
larvae mine the leaves of myrtle-croton - Bernardia myricifolia (Euphorbiaceae) (Vogt 1949b)
Life Cycle
while rearing this sp., Vogt (1949b) frequently obtained instead a chalcidoid parasite which Mr. A. B. Gahan identified as Conura near odontotae (Howard).
"The only known material for this species is that originally collected by George Vogt, either collected from the foliage of Bernardia myricaefolia (Euphorbiaceae) or reared from the leaves of this plant." (2)
Type Depository: USNM (1)
Texas considers this to be a "Species of Greatest Conservation Need" (SGCN) (4)
