Phorid flies, Pseudacteon solenopsidis, always stay in the front of their chosen victim, then quickly move to the side of the ant to inject an egg into the thorax. This female has chosen a large fire ant (Solenopsis invicta) worker and may harass it up to two minutes before ovipositing. Photo: L.E. Gilbert
