Found in a nest box

I found this "nest" inside a nest box that I was cleaning out in readiness for this spring.  Can anyone identify it please??  The grubs I saw were between about 6 and 10mm long.  It was noticable that in making the "nest" the insect/moth etc concerned had eaten onto the wood as there were many shallow "scoops" out that matched th shapes of the peanut shape coccoons. The basic meaterial seemsed to be like finely spun silk or whatever. nest-02.jpgnest-01.jpg

    These are the cocoons of the Bee  moth, Aphomia sociella.  The female of this common moth lays her eggs in the abandoned nests of  bumblebees and wasps, the ensuing caterpillars feed on the old comb, detritus, wax and any dead bodies of the former occupants. When they are  ready for pupation they up and leave and pupate together in these masses. Could be that there was a Bumblebee nest in the nest box, or in a cavity or base of the tree- there will have been one very near at least.
