Interesting creatures. They lay loads of eggs near water; the larvae are aquatic, then they emerge and go into a pupal stage.
No interactions present.
I had it down as Sialia lutaria, but it could be one of the others. I don't know much about Alderflies.
The latin name of Megaloptera was generated by iSpot. I admit I didn't even look at the result when I pressed "get recommended."
Should it be amended on iSpot, d'you think? I don't know enough to tell them they've got it wrong (well, SORT of wrong - not precise enough, perhaps).
Hi Simon, as I understand it Megaloptera is an order of insects that contains the alderflies, dobsonflies and fishflies. Your Alder Fly is probably S. lutaria; however there are 3 UK Sialis species that are very similar and I believe can only be told apart from detailed examination of the genitalia.
I always check scientific names generated by iSpot, if I don't have knowledge of them. It takes longer and I miss out on a few ID's as a result. I think these things get changed in time. I only found out about Sialis etc by getting a post incorrect.
