Un-identified grubs

[Lesley Cox]

The ones I killed with boiling water were like the hairless one taken on 9/4/11 and the pic above it, is roughly what I know as daddy-long-legs, so maybe I wasn't too far out. The one we have here in numbers maybe a different species, don't know, but very similar.

The larvae of crane fly and St Mark's fly are very similar, Lesley, mainly it is the head that is different. To confirm the exact species of these Bibio larvae it seems that I would have to carry out an anal inspection; somehow I don't think so .... The good news is that Bibio just have a one year life cycle so, when these larvae pupate into flies in spring this infestation should be finished.

But will the flies not lay eggs which will turn into larvae then into pupae.....?

Perhaps David is expecting it to rain for forty days and forty nights, in which case only two will survive?

That's next years problem, Lesley We have had the flies around for years and this is the first time i have found the grubs in the loam. Hopefully they will lay somewhere else this year.
