Title: LAU stand, block 358, 8.0 mm cavities. The 2006 generation nests are all the bee Osmia lignaria with occasional losses to mites; additional deaths in the upper cavity (#5) were to dermestid beetles and emerging generation 2005 Isodontia. In that struggle 2 Isodontia were killed by cut back in Spring 2006 and 2 emerged successfully. The cut-back and blocked Isodontia nest in cavity 5 failed completely.

Abstract: 1) Dermestids are uncommon in this Data Set, plausibly because dead material was never allowed to accumulate. 2) Nearly all species show unexplained losses, sometimes substantial, at the egg or small larva stage, but mites as an 'obvious culprit' are only conspicuously present in nearly all O. lignaria nests, some leaf-roller and some Trypoxylon lactitarse nests. (Of course it just might take only one mite or Melittobia to kill an egg.)
