Found this little work of art in our driveway but have no idea what made it. It is the entrance to an underground nest/burrow, the actual hole in the ground looks similar to an ants nest with a small hole around 5-10mm in the ground. The walls of the outer funnel-shaped entrance seem to be made of little balls of sand or mud, obviously from the dirt out of the hole. The structure stands about 3cm tall and the top of the entrance funnel would be approx 2cm across. Something was seen flying out of it then back in but we weren’t close enough to see what it really was, perhaps a wasp? Didn’t see anything else in terms of bugs and unfortunately the structure has since been destroyed (they picked a bad place to build this!)
Very interested to know what might make this tiny work of art.
I am in Hawkesbury region of Sydney, Australia.
We apologize for the delay, but responding to you has been on the back burner since we first opened your file and inspected the image. We agree that the most likely builder is a wasp though our initial thought was perhaps a crayfish burrow. Since you saw the tenant flying in and out, we would discount the crayfish possibility. We can’t imagine why a wasp would need a chimney structure like this, except perhaps to help in the location of the nest. Perhaps one of our readers will have a thought on this matter.
