I was pleasantly surprised last weekend when I found twenty-eight tenanted mines of Stigmella anomalella.

Having located a large stand of Coltsfoot (Tussilago farfara) earlier in the year, I went back this weekend lo look for the early stages of the Triangle Plume moth. The larvae feed within the seedhead of Coltsfoot at this time of year and I managed to find one larva and three pupae.
As I was hoping to find evidence of parasitism by the braconid Microgaster alebion I will have to go back and look for some more larvae, the parasitoid would not have allowed its host to reach the pupal stage.

I was out at the Denso Marston Nature Reserve looking for caterpillars on the various grasses.
Although my target species were the leaf-mining members of the Elachista family I was still pleased to find this tortrix larva hiding in spun-together blades of grass on the banks of The River Aire.
I suspect that it is the polyphagous Aphelia paleana but will rear it through to check.

This Pteromalus semotus has emerged from the larval web of White Satin Moth (Leucoma salicis) found at Hull, VC61. It is actually a hyperparasitoid, the primary parasitoid of the moth being the braconid Cotesia melanoscela.
Two other chalcids emerged from the web, a little blue one (as yet unidentified) and a Eurytomidae (probably Eurytoma).

This little feller is an over-wintering caterpillar of the White Satin Moth (Leucoma salicis). I found a couple of these amongst a batch of braconid parasitoid pupal cases collected from the poplar trees in Queen's Gardens, Hull. I have never seen the adult of this species even though it seems to be expanding its range across the county.

My second moth of the year is a bit of a cheat, it being this Dotted Border (Agriopis marginaria) that has emerged from a caterpillar collected last year at Ben Rhydding Gravel Pits.
My first moth was (appropriately enough) an Early Moth (Theria primaria) attracted to the lighted window of Hollins Hall Hotel on 23rd January 2012.
