April Warming and the Mining Bees

Saturday was the first decent warm sunny day in Wicklow this spring, and Tawny Mining Bees immediately appeared. Most of them were males, about twelve all newly hatched out, but there were two larger females giving them a wide berth.

My first photo of a Tawny Mining Bee this year, a male. The males don't look particularly distinctive and not exactly handsome and their sole objective is to mate with females, which gives them a peculiar 'culture' and distinctive weapns too, as you'll see.

It's not easy to get a good photo of a Tawny Mining Bee, particularly the males, but I finally got a decent headshot. Look at the size of those jaws!

Many mammal species have horns and antlers which allow the males to fight off other males for the right to mate with females and pass on their genetics. Similarly male Tawny Mining Bees have enormous jaws to allow them win these fights. The female is a very different insect.

Looking like a miniature bumblebee, female Tawny Mining Bees have stout reddish furry bodies and distinctive black heads. They also rarely sit still.

Under the wings you can see a very handsome shimmering abdomen covered in horizontal rows of red fur which glints in bright sunlight. A lovely insect. But they live only a very short time.

Tawny Mining Bees fly mostly for the month of April and not much beyond that. So for the next few weeks they will be very busy doing important work, which involves a huge amount of digging.
