The distribution of this species is quite patch across the state (and the country), though at some sites it can be quite abundant. Seems to have an affinity for gardens, farms, and other semi-developed areas, especially in the warmer parts of the state.
Identification: A short-haired species with a color pattern most similar to Two-spotted. T1 yellow, T2 with a central arc of yellowish brown (hence the common name). The brownish amber color of T2 is distinctive, and should not be confused with the rusty red of the formerly common Rusty-patched. Males have large eyes and extensive yellow hairs below.
Two-spotted Bumble Bee (Bombus bimaculatus): A longer haired, generally yellower bee. The yellow patch on T2 is squared-off vs. arched in Brown-belted.
Red-belted Bumble Bee (Bombus rufocinctus): A very small portion of Red-belted don’t have red or yellow beyond T2 and can be similar to Brown-belted, though the very short malar space (check) on Red-belted is a give away.
Global Status: Secure (G5)
Vermont Status: Apparently Secure (S4)
