Solitary wasp

Psenini (tribe)


About 6 millimeters in body length, colored as shown. Note long petiole linking thorax and abdomen.


This wasp was eating sweet exudates from the stems, leaves, and buds of a common sunflower (Helianthus anuus) at the edge of a vast field of heavily degraded shortgrass prairie with yucca, prickly-pear cacti, and scattered elm trees.


Very difficult to identify these even to genus from images of living specimens alone.
