A colony of brown citrus aphids under attack by aphid killer wasps. The wasp will insert its egg into the body of the aphid. When the adult emerges from its pupa, it will cut a trap door in the dead shell of the aphid.
This wasp assumed this position several times as I watched. Maybe it was cleaning its ovipositor. This year was the first time I found aphids on my tangelo tree. I was happy to see the wasps.
