Yellow larva ID please

[mrs_trellis]

A few weeks ago I was clearing out my garden shed and came across this:



The larvae are about half-an-inch long and about a tenth of an inch across. They look a bit like maggots, except that they are bright yellow, with no markings except a brownish/black head.

The egg cases (at least, I think that's what they are) are about three inches long, and made of the same sort of material as spider-nests.

Does anyone know what they are?

Could well be Meal Moth larvae.

Thanks. There was some bird food stored in the shed, so that may well be what has attracted them.
