Yorkton, Saskatchewan. Canada
More information could be helpful. Have you seen any insects coming in or out of it? has it caused you any problems? how long has it been there?
I think two weeks. Havnt seen any insect
hasn’t bothered us.
I am not sure, and I am not familiar with the fauna of that particular area, so I reassigned the question to someone who could help us out. best of luck!
This looks to be the nest of a mud dauber. If you break it open, You will see several chambers divided by a thin mud wall and there are likely paralyzed spiders in there that serve as meals for the developing wasp larva. Sounds like a horror movie, doesn't it?
