I have no idea what it is, it was on the wall behind a photo. We haven’t touched it yet and we have no idea what it is, I’ve never seen anything like it before, it looks like cocoons inside a hive..

Mystery Nest

Hi Nicole,
This really is an interesting looking nest.  It appears that the cells are made of sand.  Our best guess on this is that this might be a wasp nest of some type.  The creatures in the cells appear to be pupae.  Many female solitary wasps build nests, some of mud, that they provision with paralyzed prey that the developing larvae feed upon.  This might also be a Bee Nest that was provisioned with pollen.
  We will try to get a second opinion from Eric Eaton.

Mystery Nest

Eric Eaton agrees with our assessment.
Looks like wasp or fly pupae inside the individual cells.  Rearing them out to adulthood would tell you what they are.  Otherwise, I need to know what, if any, debris is in each cell with them.  Pollen = bees; insect or spider parts = wasps; other, or none probably = flies.
Eric

Thanks Eric,
We came to the same conclusion.  We responded about the wasp and bee possibilities, but we only thought the fly possibility.
