Colour patterns do not diagnose species: quantitative evaluation of a DNA barcoded cryptic bumblebee complex.

Cryptic diversity within bumblebees (Bombus) has the potential to undermine crucial conservation efforts designed to reverse the observed decline in many bumblebee species worldwide. Central to such efforts is the ability to correctly recognise and diagnose species. The B. lucorum complex (Bombus lu...
