Red-belted bumble bee

Status: Common

Select food plant genera: Cirsium, Melilotus, Arctium, Trifolium, Aster, Tanacetum

Tongue Length: Short

Distribution: Broadly distributed across the northern half of the U.S. and throughout the southern Rocky Mountains and the Sierra Nevada

Highly variable coloration; can be confused with B. melanopygus, B. bifarius, B. huntii, and B. sylvicola

Similar to many color patterns shown by both western and eastern North American bumble bees, but small bodied, short haired and with a very short face.

Mid leg basitarsus with the distal posterior corner rounded. Cheek length distinctly shorter than broad. Many other combinations of these color patterns are known, but the hair of T2 is almost always with at least a yellow crescent anteriorly (only rarely very much reduced). Hind basitarsus with the posterior margin evenly but not strongly arched. Hair length short and even, body size small.

Discussion. B. rufocinctus is most closely related to the European B. cullumanus and more distantly related to members of the subgenus Separata-bombus. In addition to the characters in the subgen¬eric diagnoses, B. rufocinctus differs from B. grtseo-collis and morrisoni in having longer, more sparse hair and more shiny integument This species varies greatly in color pattern (Figs. 105, 132). As a consequence, many infraspecific names have been applied (Milliron, 1973b). How¬ever, the color patterns do not vary in any ecogeo-graphic pattern. Several color patterns occur at sin¬gle localities (Thorp, 1962) and even in the same nest (Stephen, 1957). Thus, the application of sub¬species names to these patterns is inappropriate. The biology of this species has been discussed in considerable detail by Hobbs (1965b). He found females of all three species of Psithyrus (suckleyi, insularis, and fernaldae) and eggs laid by some P. insularis in nests of B. rufocinctus. However, he was unable to determine whether any Psithyrus were reared to adults. He also found that a conopid fly, Physocephala texana, killed a founding B. rufocinctus queen.

Description. Queen small, worker and male very small to medium. Head rounded; malar space very short, about half as long as wide. Tongue short, shortest of North American species;ocellislightlybelowsupraorbitalline.Eyes moderately enlarged and slightly bulging in male. This species is more variable in colouration than any other species in eastern North America.

Female. Facial pile with mixed black and yellow hairs, vertex yellow. Thoracic pile yellow, except for black pile in the interalar area, which may form a clearly defined black interalar band, a black band with yellow pile intermixed around wing bases, or a small black spot. Tergum 1 yellow, T5 and T6 black. Pile colouration of remainder of the abdo- men highly varied in two areas: posterior margin of T2 and all of T3, red (red morph) or black (black morph); and T4, red (Fig. 5a) or yellow (Fig. 5b) in red morph, and black (Fig. 5c) or yellow and black (Fig. 5 4 in black morph. Some females of red morph with yellow pile on lateral margins of T5.

Male. Colour patterns generally as those described for females of red and black morphs. Tergum 1-T2 yellow in both morphs. In red morph, T3 red, T 4 T 5 red (Fig. 5e) or mostly yellow (Fig. 5&, TGT7 black in most specimens but red or yellow in a few specimens.Inblackmorph,T3-T4 black,T5black(Fig.5g)or yellow (Fig.5h),although some specimenshave yellow pile only on lateral margins, TGT7 black in most specimens.

The colour of T2 and T3 on the one hand and T4 on the other apparently varies independently and bees with different patterns are often produced by a single colony (Owen and Plowright 1988).

Description. Queen. Length, 18.0 mm; width at wing bases, 7.5 mm; abdomen, 10.0 mm, width across T2, 9.0 mm; front wing length, 15.0 mm, width 5.0 mm. Head: Frontal outline (excluding mouthparts) roundly trapezoidal, the median height about equal to the widest part, broadly rounded at the temples, vertex broadly arcuate; vertical region nearly flat and mostly covered with small to medium punctures; ocular half of ocellocular area covered with small and medium punctures, the ocular half for the most part smooth; com­ pound eyes only slightly more broadly rounded below than above, their inner margins nearly parallel except slightly convergent above; ocelli of medium size situated in a weak arc just below the supraorbital line and separated from one another by somewhat less than their diameters; interocellar line only noticeably greater than the ocellocular line; malar space about f as long as distance between (and including) mandibular articulations, its surface weakly unevenly convex and with few inconspicuous punctures; labrum little more than twice as wide as thick, its ventral margin for the most part arcuate, the labral shelf irregularly sculptured and not very sharp, the tubercles rather low flattened and irregularly sculptured beneath, their inner summits separated by a somewhat shallow intertubercular depression about equal to the combined lengths of F2 and F3; flagellum about If times longer than scape, FI nearly equal to the combined lengths of F3 and F4, F3 noticeably longer than the quadrate F2; clypeus rather evenly but not strongly convex, its median height about equal to f the widest part near the base, well covered with small and medium punctures. Legs: Mesobasi- tarsite subrectangular and about 3 times longer than widest part which is noticeably wider than the length of longest hairs of the posterior fringe, the outer surface nearly flat, the distal angles both not sharp and about equally extended with a shallow emargination between; outer surface of hind tibia microscopically granulose, with a weak longitudinal convexity just anteriad of the middle, the widest part about equal to longest hairs of corbicular fringe; metabasitarsite subrectangular, about 21 times longer than widest part which is nearly twice as wide as the length of longest hairs of the posterior fringe, outer surface broadly and shallowly concave longitudinally, the posterior margin evenly but not strongly arcuate from base to distal end which is nearly subtruncate. Pubescence: Rather short, fine and dense, only slightly longer on the posterior region of scutellum; mesobasitarsal posterior fringe of medium length along the proximal two-thirds of margin, the hairs straight and rather loose, becoming much shorter distally; corbicular fringe somewhat dense, comprised of moderately long weakly curved hairs except those at distal end much shorter and strongly arcuate; metabasitarsal posterior fringe not dense, composed of longest weakly bent hairs only along about the proximal one-third, becoming much shorter beyond. Color: Head predominantly black with considerable yellow on occiput, some intermixed on vertex, and some fine pallid pile inter­ mixed on the face; thorax yellow with some dark pile near leg bases and a poorly defined black interalar band that is widest at the middle; abdominal T1 and basally and most of medial area of T2 yellow blending to ferruginous laterally and distally, T3-4 ferruginous, T5 black with trace of ferruginous laterally, T6 black, the abdominal venter mostly blackish with few ferruginous tinged hairs especially along the distal sternal margins (c/. under Comments for references to the most common forms of chromatic variants in this species, including those in the hypotype series but not detailed above); legs black but sometimes with a ferruginous tinge to some hairs especially those of the fringes.

Worker. Length, 12.0 mm; width at wing bases, 5.5 mm; abdomen, 6.0 mm, width across T2, 6.0 mm; front wing length, 11.0 mm, width, 3.5 mm. The structural characters in this caste are relatively very similar to those of the queen in proportions and form. Size varies widely from individuals that are only about one-half as large as given to those that are some­ what larger, but it is uncommon for a specimen to attain the size of even a small queen, unlike the situation existing in several other species. The color patterns and chromatic variability parallel those found in the queen (cf. under Comments).

Head: Frontal outline (excluding mouthparts) roundly trapezoidal, broadly rounded at the moderately narrow temples and only weakly arcuate across the vertex, about as wide at the widest part as the median height; vertical region nearly flat, unevenly covered with small (mostly follicular) punctures and only slightly inclined toward the occiput; ocelli of medium size, located in a weak arc distinctly below the supraorbital line, noticeably closer together than their diameters; ocellocular area little wider than the diameter of a lateral ocellus, the ocular half with few small punctures, the ocellar half smooth; interocellar line nearly twice as long as the ocellocular line; compound eyes somewhat swollen, about equally rounded above and below, their inner margins nearly parallel; malar space little more than \ as long as distance between (and including) mandibular articulations, transversely weakly convex, mostly smooth; labrum little more than twice as wide as its greatest thickness, its ventral margin nearly straight except arcuate at the corners, the callosities very weak and not separated by a deep depression; flagellum little more than twice as long as scape, FI subequal to F3 which is nearly li times longer than subquadrate F2. Legs: Mesobasitarsite nearly rectangular, its widest part about equal to the length of longest hairs of the posterior fringe, the posterior margin nearly straight, the outer surface only weakly concave longitudinally, the distal end subtruncate with the somewhat sharper distoanterior angle extended only slightly beyond the distoposterior one with a very shallow emargination between; metabasitarsite with widest part about equal to the length of longest hairs of the posterior fringe, the outer surface for the most part broadly concave longitudinally, the posterior margin rather strongly arcuate proximally, beyond nearly straight, the more swollen anterior margin evenly but not strongly arcuate from base to distal subtruncate end of segment. Pubescence: Similar to that of the queen but for the most part slightly less dense; mesobasitarsal posterior fringe of medium length, not dense, longest hairs along proximal third and gradually diminishing in length to the distal end, all straight or nearly so; hind tibial posterior fringe composed of moderately long, not especially dense hairs that are mostly weakly arcuate, the distal ones more strongly so, much of the outer surface of hind tibia devoid of pubescence; metabasitarsal posterior fringe rather long and loose with mostly weakly bent hairs the longest of which are just proximad of the middle of margin, those at both ends of the segment being shorter. Genitalia and seventh and eighth abdominal sterna (PL XIX). Color: Head mostly black with some yellow (or yellowish) intermixed on the vertical region, face, and lower gena; thorax yellow (somewhat duller ventrally) with a rather broad interalar black band that is not sharply defined; legs mostly black with some pallid (yellowish) pile near their bases and yellow on the dorsal distal half of hind femora, abdominal T1 yellow, T2 yellow except for a ferruginous tinge distally and distolaterally, T3-5 mostly ferruginous with some slight admixture of yellowish hairs at the extreme sides, T6-7 mostly black with an intermixture of some ferruginous tinged hairs, the abdominal venter largely blackish with some yellowish pile especially distally on the median sterna (for color variation cf. under Comments). Wings rather lightly infumated, the discal area often slightly paler.
