Syrphidae
Eristalinus aeneus has eyes like that, but I don't know if any others have similar eyes; Sceliphron caementarium provisions with spiders so this must be the nest of a different wasp

 
flies found in a wasp mud nest cell
I found this and other mud nest cells under a concrete bridge over a stream. The mud nests looked like those of Sceliphron caementarium. I also thought these wasps provision only with spiders, leaving me wondering if they would use any other arthropods. Are there other wasps that make nests like those of Sceliphron caementarium, or maybe more likely, wasps that take over their nests?
