Bumble bee. Wasps are smooth and the ordinary ones have very distinct
stripes as well as the equally pronounced famous wasp waist.

Non-bumbley bee, I think you'll find. But yes, the more I look at it the
more I'm inclined to agree.

Also, the fact that it was mostly asleep and almost underground would also
seem to imply a beelikeness.
