Pipe organ mud dauber

Trypoxylon politum


Insect nests spotted on the underside of the observation tower at Huntley Meadows Park. The nests are made of mud. These nests were built by a type of wasp known as Pipe organ mud daubers. Notice the small spider that is shown in the upper-right part of the nest in Photo 2. Pipe organ mud daubers "...stock their nests with spiders, which serve as food for their offspring."

Thanks for the helpful comment, Jeffrey! I plan to revisit the nests during early summer to look for holes in the pipes indicating new wasps have emerged from sealed chambers within the pipes.

Its a Mud Dauber they build these chambers and stuff them full of spiders that they paralize for feeding the egg they lay in each chamber when it hatches
