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.
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.
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.
