Exuvia corner

[Geoffrey Dabb <>]

Peter Cranston and Alison Rowell have confirmed exuviae of a smaller species of dragonfly.  Still there this morning, just a couple  -  more than one exuvium anyway.  Incidentally photo taken at about 45m distance

Thanks Geoffrey, this shows that they are indeed the cast skins (exuviae) of nymphs of dragonflies, albeit from a small species. Damselflies would have a longer tapering tail.

Thanks for your interest Peter.  See attached. I might try for further shots.  Damselflies?  g

Hi Geoffrey,
Can you send me a high res image ? The two 'discussant' insects seem too small relative to the swallows for either odonate or cicada, and shape and pigment seem to be of live insects.  Pete

A chance snap of a well-known feature at Kelly Swamp on Monday morning revealed what I take to be the discarded cases of dragonfly nymphs apparently clinging to the underside of an over-water bird perch erected by Michael Maconachie, keen dragonfly photographer of years past. Or could they be cicada cases?
