"This wasp mimic was very active/hyper and very wary and took a good while to nab...(2 days)... This animal was feeding very actively on the blooms of an oregano bush and also could be found on dill blooms as well. It was doing its best to look like a wasp. When captured it would attempt to "sting" you or at least make the motions of doing so."
