Question

tiny mud pot
A customer at our lodge found this at about 6000' elevation in southeast Utah, Pinion/Juniper forested, <10" annual precipitation. I am the resident biologist (Wildlife Bio BS Colorado State U 1983 and 1 class in entomology) :-) and have been challenged with identification. Help!

Answer
Hi Jim; A perfect example of the work of a Sphecid wasp called a mud dauber.  Without seeing the wasp I cannot tell you the Genus ; possibly Sceliphon. Daubers are solitary wasps and lay eggs in the mud nest along with paralyzed spiders to feed the maggot. I found a photo similar to this one at this web site.
