English: Robber fly (Cyrtopogon lateralis) during oviposition. The egg-laying took place in dry, sandy-loamy soil near a raised root area of a fallen oak tree at the southern edge of a forest. The forest was in a natural area called "Brückerwald und Hußgeweid" (FFH area 5119-301) in Amöneburg, Middle Hesse, Germany. Shown here are three individual scenes. First, the video shows the entire laying cycle where the female robber fly laid eggs 20 times interrupted only by short breaks and flights to other storage locations on the rootball. The cycle ends with a cleaning phase and subsequent food intake in a neighbouring area.
