Files in this Data Supplement:
Movie 1. A fifth-instar tobacco hornworm (Manduca sexta) crawling on a dowel in a kinematic chamber. Two such views of an animal crawling were synthesized into a 3-D kinematic mapping from which position and velocity information could be extracted. Points of interest on the exterior body wall corresponding to points on the musculature were marked with fluorescent beads. In this case, beads demarcate insertions of DIM muscles on proleg-bearing segments and reference points on proleg tips.
Movie 2A,B. A fifth-instar tobacco hornworm (Manduca sexta) standing on a flat surface responding to a noxious stimulus (squeeze on the terminal segment) with a strike reflex. A single overhead view was synthesized into a 2-D kinematic mapping from which muscle position and speed could be approximated. Fluorescent paint was used to mark body boundaries on one side of the animal. Separate video recordings were made for strikes (A) toward and (B) away from the marked side.
