Preadult Mayfly

Today I saw a strange insect resting on the kitchen window. It was colored in different shades of brown. Its wings were held straight out at the back and together, and it had amazingly long front legs. There browny blotches on its wings. I looked it up and discovered it was from the family Ephemeroptera, that is, it was a mayfly. On reading further I discovered it was a male and, from its appearance, had recently emerged from a nymphal case, and had not yet reached the final stage of its metamorphosis known as the sub-imago – it is a winged preadult life stage unique to the mayfly among all insect species. It usually rests among vegetation waiting for the final moulting stage to occur revealing the fully clothed mayfly or spinner as they are also known. Sadly, their life is very short: they will mate and if female lay eggs and in a just a few hours they will probably be dead.

Scorpion Fly

Today while working in the garden near the paddock I saw a scorpion fly – he was entirely fascinating. I knew instantly what he was because of his upturned scorpion-like tail, also his head looked different from a normal fly. I watched him for a while, then he went about his business, and I went about mine.

It is sad to relate there are not as many butterflies about again this year, actually even less than last year, and if one prettily appears it is often seized upon and eaten, often as not by a robin.
