Explanation of Names
Trypoxylon (Trypargilum) texense Saussure, 1867
from the New Latin texense ('Texan, of or pertaining to Texas')
This species is rather distinctive for the combination of its bright golden pubescence and reddish basal (4-6) antennal segments.(1)

The ground color of the body is black, with orange to reddish markings on the antennae (as above), mandibles, palps, tibiae, tarsi, and the second (occasionally also first) gastral segment. Dense, golden pubescence covers the face, posterior margin of the pronotum, the edges of the scutum, and posterior angles of the propodeum.(1)
central and southern US: west to NM(1) and east to FL(2)
(also occurs in northeastern Mexico and Jamaica)(1)
April to October(1)
Nests are provisioned with spiders from the families Oxyopidae, Araneidae, Tetragnathidae, Thomsidae, and Salticidae. Each cell may contain between 8-25 prey (15 on average).(2)
Life Cycle
T. texense repurpose existing nests with rather little selectivity. They are known to nest in abandoned mud nests, such as those of Sceliphron caementarium, or abandoned burrows, such as those of Tachysphex apicalis, Melitoma grisella, and Anthophora occidentalis. Following oviposition, the cells are sealed with either a single or double plug of mud. Males frequently guard the nest while the female is away, such as when hunting for nest provisions.(2)
