Overview

Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141. FEMALE—Length 11 mm.; entire body brilliant blue-green; mandibles testaceous at extreme base, apical half piceous; apical third of clypeus black, rather deeply and coarsely punctate, basal portion green, with punctures much closer but still deep and coarse; supraclypeal area rather closely and coarsely punctate on each side of midline; face above antennae very finely rugoso-punctate, becoming somewhat more coarsely reticulate laterally; cheeks coarsely striate; pubescence of head and thorax pale ochraceous above, becoming more whitish below; scutum and scutellum shining, with scattered, rather sparse, deep punctures between which are very much more minute and close punctures; pleura coarsely reticulate, metapleura more finely striate; dorsal area of propodeum rather coarsely striate, with an obscure, median triangle where the striae are more irregular and fine, lateral faces finely and rather irregularly striate, posterior face with oblique and irregular, rather indefinite striae; coxae more or less greenish, legs otherwise largely piceous, but front and mid femora with small, apical, yellow spots; tegulae yellowish, with a small, inner, greenish spot anteriorly and a more fuscous spot posteriorly; wings hyaline, veins and stigma yellowish; abdominal terga very finely and closely punctate, pubescence of the discs almost entirely whitish, 2-4 with basal, pruinose, whitish bands, beneath which the punctures are relatively sparse but deep and distinct, pubescence of apical tergum fuscous. MALE—Length 9-10 mm.; head and thorax brilliant blue-green; abdomen piceous, with conspicuous yellow bands; mandibles yellow, with piceous tips; labrum and the narrow apical margin of clypeus yellow, clypeus green basally, more or less blackened between this and thu yellow apical margin, punctures rather coarse but shallow except basally where they are fine and close; supraclypeal area strongly protuberant, finely rugose; face above antennae densely and finely rugose; cheeks finely striate; scape and pedicel black, flagellum brownish-testaceous beneath, blackish above; pubescence of head and thorax ochraceous above, becoming whitish below, with some intermixture of blackish hairs above; scutum dull, densely and finely rugoso-punctate, scutellum more shining, punctures very fine and close but distinct; pleura rather finely reticulate, metapleura more coarsely, irregularly reticulate; dorsal area of propodeum with a rather distinct triangle which is quite coarsely reticulate, more finely rugose on each side, lateral faces finely rugoso-punctate, posterior face irregularly reticulate; tegulae yellowish exteriorly, becoming piceous on inner side, with a greenish anterior spot; wings hyaline, stigma brownish, veins more piceous; coxae more or less greenish, trochanters black, femora and following leg joints yellow, but front femora with posterior face largely piceous, mid femora with a similar, large, piceous blotch and a subapical, smaller one, hind femora with a small basal blotch and a somewhat larger, apical one, these quite slender, with a subapical, ventral tubercle, the tibiae with the posterior side largely piceous; basal abdominal tergum blackish basally and apically, with a rather narrow, median, transverse, yellow stripe which is rather strongly narrowed medially, following terga with basal yellow bands, apical, blackish portion rather strongly suffused with greenish, this more marked laterally, punctures very fine and close throughout, pubescence pale on basal segment and yellow areas of the following segments, becoming somewhat blackened on apical portions of the discs; abdominal sternum 4 swollen apically on each side, this area with a broad, triangular emargination which is largely occupied by the flat posterior border of the plate, 6 flat and unmodified; ventral lobe of gonocoxite broad and expansive, with an apical fringe which is much elongated at extreme sides; gonostyli with a slender apical stylus, tip of which is abruptly flexed, with a median flattened, dorsal, triangular lobe, a slender, ventral projection, and a basal slender finger- like curved projection; penis valves slightly grooved medially, base rather abruptly expanded at this point. DISTRIBUTION—British Columbia and Washington to Maine, south to Mexico and Georgia; April to November. FLOWER RECORDS—Aster, Cerasus, Fragaria, Geranium, Prunus, Rubus and Senecio. Robertson (1929) records texanus on the following: Amorpha, Brauneria, Cassia, Cephalanthus, Cirsium, Coreopsis, Helianthus, Lepachys, Petalostemon, Pycnanthemum, Rhus, Verbena and Veronica. The use of the subspecific designation of this form is made necessary by the occurrence of four other forms in California that are recognized as subspecies of texanus.
