Measured ~12 mm in length (ventral side shown with ruler image while still wet from the pond water). The wing membrane is hyaline and veins are yellow/gold. Body long, slender, black with yellow markings, legs mostly yellow except for dark femurs dorsal side, yellow clypeus and mandibles except dark tip of tooth. Had a curved "pseudostinger" at the tip of the abdomen, upwardly curved, "hook-like" terminal spine (= "uncus") (BugGuide descriptions for males). Also, females in the Thynnidae family are wingless. Hind tibia appeared to have short, small, tooth-like projections. Rescued from a garden pond, fully recovered, and flew off. Apparently parasitoids of white grubs (scarab larvae).

~ 1 mm body with antennae same length as body. Was running on the edge of an empty white bucket with an outside temperature of 106 degrees F. ID as suggested by AI based on 1 prior ID in a nearby vicinity. According to WaspWeb Tetracneminae are parasitoids or hyperparasitoids of insect and arachnid eggs and larvae.

~9 mm in length. Running about in the soil. May have moved due to watering of a garden area. Played dead for a bit; remaining motionless even if gently tapped (last photo), then ran swiftly again to hide.
