Overview

The following material taken with permission from: Mitchell, T.B. 1962. Bees of the Eastern United States, Volume II. North Carolina Agricultural Experiment Station. Tech. Bul. No.152, 557 p.

Florilegus closely resembles Melissodes and may be mistaken for it. The mandibles, however, have a subapical inner angle or tooth in both sexes, and the maxillary palpi are 5-segmented. The clypeus is black and slightly separated from the margin of the eye in the female, while in the male it is yellow and practically contiguous with the eye margin. The scopa is finely plumose. Sternum 7 in the male is distinctive, having a median longitudinal ridge, the apex produced somewhat beyond the margin of the plate. Tergum 6 is distinctly angulate on each side at the base, and tergum 7 is spinose laterally, the pygidial plate entire, the lateral margins not notched.

MALE—Length 9.5-12.5 mm., breadth of abdomen 3.5-5 mm.; black, the clypeus bright yellow, labrum and mandibles largely black but mandibles with an apical testaceous maculation; antennal flagella brownish-testaceous beneath, piceous above; legs dark, tarsal segments becoming brownish-testaceous apically, mid and hind spurs pale yellowish; tegulae brownish; wings very faintly infuscated, veins brownish to piceous; rims of abdominal terga very narrowly yellowish-hyaline; cheeks considerably narrower than eyes; clypeus slightly protuberant, its median length somewhat greater than half the distance between eyes below; eyes rather strongly convergent below; mandibles with a small, inner, subapical tooth or angle; basal segment of flagellum slightly longer than pedicel, segment 2 about five times longer than shorter side of the 1st; punctures of clypeus quite coarse, deep and somewhat separated along upper margin, becoming more finely and closely punctate apically; median length of labrum considerably less than breadth, rather broadly rounded, slightly emarginate medially, punctures fine, close and deep; supraclypeal area rather dull, punctures irregular but rather well separated; lateral areas of face below antennae dull, very finely and closely punctate, dorsal areas more shining, punctures somewhat coarser, deep and distinct; cheeks very finely and closely punctate beneath rather dense pubescence; scutum shining between quite coarse and deep punctures, these somewhat separated posteriorly near mid-line, closer laterally and anteriorly; scutellum shining, somewhat more finely but uniformly closely punctate; pleura dull, tessellate, punctures rather coarse and close; posterior face of propodeum shining, punctures rather fine but deep and close, dorsal area polished below, becoming rather coarsely, deeply punctate across upper margin, lateral faces rather dull, punctures shallow but very close and rather fine; abdominal terga well punctured throughout, punctures quite coarse and deep but well separated on the more basal terga, becoming much finer and closer laterally, punctures of apical impressed areas only slightly finer than those toward base, somewhat finer and much closer on the more apical terga, being crowded and very fine laterally on 3-6; tergum 6 with a conspicuous apical angle at each extreme side, and tergum 7 with a corresponding, more slender spine; pubescence copious, elongate and quit dense on head and thorax, largely pale ochraceous on head, scutum with considerably fuscous pubescence across posterior half, and a few shorter dark hairs on scutellum medially, otherwise thorax largely pale ochraceous pubescent; legs entirely pale pubescent; basal abdominal tergum with copious, elongate, pale ochraceous pubescence across base, disc with shorter but erect and quite conspicuous black pubescence; tergum 2 with a dense, whitish, basal fascia that is covered in part by the preceding tergum, the disc black pubescent; tergum 3 black pubescent across base, with a quite broad and dense, median, whitish fascia, the apical impressed area black pubescent; tergum 4 with rather copious, elongate and erect, black pubescence, with a dense whitish fascia on each side which is narrowly connected across the disc with some obscure pale tomentum, the median area of the impressed margin black pubescent; tergum 5 broadly white pubescent apically on each side of mid-line, disc with long, erect, black pubescence; terga 6 and 7 entirely black pubescent; median length of pygidial plate somewhat greater than basal width, margins carinate, rather strongly converging to the rather broad, subtruncate apex; sterna 7 and 8 and genital armature as shown (fig. 78).

DISTRIBUTION—Colorado to New Jersey, south to Texas and Florida, May to August, but with early and late records in April and September in Florida.

FLOWER RECORDS — Melilotus and Pontederia. Recorded by Robertson (1929) on Asciepias, Blephilia, Cassia, Cephalanthus, Dianthera, Lippia, Lythrum, Psoralea, Pycnanthemum, Teucriurn and Verbena.
