What are crane flies?

Crane flies are not spiders but as the name suggests a re a fly.

Why do they appear in autumn?

Commonly known as ‘daddy-longlegs’ in the UK, crane fly adults bump clumsily around our homes after being attracted to lit windows at night.

Their sudden appearance, usually in autumn, is due to a mass hatch of maggots. Called leatherjackets, the larvae have passed their time munching roots in damp soil, and look fairly ordinary save for, as Erica McAlister puts it in The Secret Life of Flies, “their most exquisite anal breathing tubules”. Sadly, due to pesticides, huge swarms of crane flies are mostly a thing of the past.
