Mesostenus gracilis hatching larva. The larva hatches from its egg and then feeds on a nearby unhatched egg before wandering around the host pupa, occasionally stopping to feed. Time-lapse 15 frames/sec, 30 sec intervals.

Mesostenus gracilis molting larva. Note the ripple that appears to move down from the head of the larva, and the exuvia that is left behind. Time-lapse 15 frames/sec, 30 sec intervals, 4.2 MB asf file.

Mesostenus gracilis larva spinning cocoon. This is only a small portion of the total time spent on this activity. Time-lapse 15 frames/sec, 30 sec intervals, 9.9 MB asf file.

Mesostenus gracilis larva depositing meconium. Time-lapse 15 frames/sec, 30 sec intervals, 2.9 MB asf file.

Mesostenus gracilis adult emerging from cocoon. Time-lapse 15 frames/sec, 30 sec intervals, 1.4 MB asf file.

Mesostenus gracilis adult and "spinning" pupae. The pupae have developed within navel orangeworm cocoons, and gyrate when disturbed. 3.4 MB Quicktime mov.

Mesostenus gracilis "spinning" pupa. A close-up of gyrating parasite pupa. 1.5 MB asf file.

Goniozus species stinging a navel orangeworm larva. The wasp will later lay several eggs on the paralyzed larva, and guard them as they hatch and feed on the host. 13MB mov file.
