Your letter to the bugman:  Dear Mr Bugman,
I come to ask you about the small nest that’s formed on my ficus tree. I live in the Southern Hemisphere and it’s summer right now. I suspect it’s some kind of wasp nest. What can you tell me about it? Also, should I just leave it alone?
It’s about 5 cm x 4 cm x 4 cm by the way

Potter Wasp Nest

Dear Sofi,
You are correct that this is a Wasp Nest, and since it is a non-aggressive solitary Potter Wasp, there is no need to fear it or to remove it.  Potter Wasps or Mason Wasps in the subfamily Eumeninae construct nests of mud.  Here is a BugGuide image for comparison.

Thank you!!! It’s so cool you were able to identify it!
