Andrena tibialis (Kirby,1802)

Description and notes

One of the largest Andrena species in Britain. It is a uniformly brown bee with reddish yellow hind legs, especially noticeable in females, where the yellow scopal hairs accentuate this colouring. It belongs to the group with a raised crest around the rear of the propodeum; this can often be seen with a hand-lens when examining specimens in the net. Males may be found patrolling along hedge-lines and around isolated bushes, flying at about head height, presumably searching for newly-emerged females.
