An intriguing specimen - the thorax and abdomen are of the recently described short-faced bumblebee Bombus rainai, but the head is glued on from a long-faced bumblebee, although two of the ocelli are almost completely fused - a new species???

My, what BIG TEETH you have! - the evolution of specialist flower-robbing bumblebees (Alpigenobombus) world-wide - but what are the costs & benefits of nectar robbing for these bees?

How did bumblebees spread around the world? Turns out Skorikov pretty much nailed it 100 years ago. Find out more:

Barcodes appear to show a flush of unrecognised species among Mexican bumblebees, but at least some of them may be explained by barcode-like pseudogenes - we begin to explore this for the weisi-complex (pic of B. weisi worker in Chiapas 2023)

pdf now available from ResearchGate - keys and 337 colour-pattern diagrams, designed for precision IDs in the lab, this is not a field guide (a lockdown project so no opportunities for pics of live bees or characters)
