For the Rusty Patched Bumble Bees, the initial a couple of intestinal segments is purple, as well as the remaining abdomen are black colored (come across pictures lower than). This color pattern is pretty exactly like added Maine types, however the distinguishing characteristic was a corrosion-coloured “patch” toward upper middle a portion of the 2nd abdominal section. Either the spot are browner than rust-colored, but it is always restricted to your second abdominal part and you can bordered because of the yellow along the sides and you may base.

Even when rust color can be entirely on other areas, you will find generally speaking significantly more of it with the gut of a purple Belted than the separated quick patch into Rusty Patched.

It kinds is known generally on the southern 1 / 2 of this new county and is perhaps not a species that’s seem to seen.
