Day One for Megaselia scalaris larvae

This is from joint project with an Environmental Health Science student, Dewitt Aristotle, in regards to survival and effect of mutagens on Megaselia scalaris.

This video shows the newly emerged larva of M. scalaris feeding on Drosophila agar. The size of first instar larva was approximately 0.5 mm  but the cephalopharyngeal skeleton was about 0.1 mm. It was interesting to observe the movement of cephalopharyngeal skeleton which i could not describe it accurately at this moment. However, we can clearly see that both mandibles moved inward while the labial sclerite was retracting during feeding.
