Timothy Tortix larva

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.

Pteromalus semotus

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).
