This morning there was a crane fly on the outside of the window, allowing me a view of its ventral side. Interestingly, it had another teensy insect on its leg — it was so small that I couldn’t tell if it was tangled or what. Was it a baby crane fly? How big are they when they metamorphose into adults?

In some places, crane flies are called mosquito hawks or “skeeter-eaters,” despite the fact that they don’t prey on adult mosquitoes or other insects. Adults have a lifespan of 10 to 15 days. The larvae of crane flies are commonly known as leatherjackets, and usually feed on decaying plant matter.

Crane flies first emerged in the Middle Triassic period, approximately 245 million years ago, making them one of the oldest known groups of flies. To date, scientists have described over 15,500 species across more than 500 genera.
