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 11-13 mm.; eyes convergent below; length of malar space nearly one-half its breadth; facial foveae distinct, but very small, subtriangular; antennal segments nearly as broad as long; clypeus rather flat, dull and tessellate, sparsely punctate except at extreme sides where the punctures are close; punctures sparse in center of supraclypeal area; pubescence greyish-white, intermixed with fuscous on face. fuscous on vertex and dorsum of thorax; lateral angles of prothorax acute but not spine-like; metapleural protuberance low, not carinate; wings subhyaline, veins and stigma fuscous or ferruginous, 2nd submarginal cell slightly exceeding 3rd; antennae, tegulae and tarsi reddish fuscous; spurs testaceous; scutum closely punctate and dull over anterior half, punctures becoming sparse and surface shining in center of posterior half; anterior half of scutellum shining, largely impunctate, posterior half closely punctate; pleura shining, the punctures deep and quite coarse, well separated but not sparse; anterior coxae not spined; length of hind basitarsi about three times the breadth; abdominal terga uniformly, closely, deeply and finely punctate, punctures becoming more minute on apical segments, apical margins of the terga only very obscurely and narrowly reddened, distinctly depressed, with dense, white, apical fasciae, interrupted medially on the basal segment, lacking on the 5th, discal pubescence very short and inconspicuous on abdominal terga beyond the 2nd.

MALE—Length 9-10 mm.; eyes convergent below; malar space slightly longer than broad; antennae dark, segments twice as long as broad; clypeus flattened in central portion, shining, with but a few sparse, scattered punctures; pubescence greyish-white, intermixed with fuscous on face, fuscous on vertex and dorsum of thorax; lateral angles of prothorax acute but not spine-like; metapleural protuberance low, not carinate; wings subhyaline, veins and stigma fuscous or ferruginous, 2nd submarginal cell slightly exceeding 3rd; tegulae and tarsi more reddish; spurs testaceous; scutum shining, punctures deep and rather coarse, quite close but distinct laterally, well separated but not sparse medially; scutellum shining, punctures sparse, in large part much finer than those on scutum; pleura shining, with deep, rather coarse, well separated punctures; basitarsi slender; abdominal terga shining, the more basal segments deeply, distinctly and closely punctate, becoming more minute and slightly more sparse on the more apical segments, apical margins of terga depressed, obscurely reddened, with dense, entire, white fasciae, discal pubescence very short and inconspicuous on abdominal terga beyond the 2nd.

DISTRIBUTION—North Carolina, Georgia and Tennessee, north to Michigan, New York, the New England states, and Nova Scotia; mid-July to mid-November. Stephen states that the range of compactus extends westward to Kansas and southern Arizona.

FLOWER RECORDS—Aster, Baccharis, Chrysopsis, Eupatorium, Rudbeckia and Solidago. Robertson (1929) records compactus on Bidens aristosa B. frondosa, B. laevis, Boltonia asteroides, Eupatorium serotinum, Helenium autumnale, Helianthus tuberosus, Rudbeckia laciniata, R. triloba, Solidago canadensis, S. nemoralis, S. rigida and 7 species of Aster.
