Elachista maculicerusella.

This was one of my target species for this year and I was lucky enough to find three tenanted mines on Reed Canary Grass at Tag Meadow on Tuesday. One pupated yesterday on the outside of its mine as they tend to do. I think Paul has reared this species before but it's a new for me.I'm hoping to find more Elachista mines over the coming weeks but it's identifying the various sedges and grasses that's the problem!

So many species out there that are so easy to find - it's just knowing when and where!

Well done Charlie.

Please keep any parasitoids that emerge from your finds, particularly from Elachista. I would certainly be interested.

Mark Shaw is looking at the taxonomy of the species of Braconidae: Microgastrinae (genus Pholetesor, sometimes known under the name Apanteles) that parasitise leaf mining Lepidoptera in Britain and Europe, especially all genera of Gracillariidae and Elachistidae but also a few others including Psychoides (Tineidae)and Emmetia (Tischeriidae).

Pholetesor are often very numerous parasitoids of these groups. It has become clear (Shaw, in press, Entomologist's Gazette) that DNA studies will be needed in order to understand species limits in Pholetesor

Hi Derek,

As maculicerusella was one of my target species for this year anything other than a moth emerging may meet a swift demise but I will try my best.

I was wondering if my pupa is safe now or whether parasitica can still emerge from the pupal stage?

I think you should be home and dry now with this one, although you can never say never!

Braconids tend to emerge during the larval stage but some ichneumonids and chalcids can emerge from pupae.

I found some more mines and a pupa on Reed Sweet-grass today.One looks a bit like Elachista poae but is probably something more common.They certainly make for a lot of head scrarching!
