Why do caterpillars walk in a line?

They travel in long lines of hundreds or more in search of food or a suitable place to begin the transformation into their adult form: the bag-shelter moth (Ochrogaster lunifer). Together they present a formidable number of irritant hairs to predators and the conga line helps prevent them getting lost.

A group of masked birch caterpillars hang out on a leaf, possibly communicating via vibration. For instance, once the visitor joins the silken shelter, the insects continue using vibrations to communicate with each other about feeding and maintaining the shelter.

Do worms make noise?

But it wasn't until researchers brought them to the lab that they noticed how noisy they were. Researchers say the popping sounds emitted by the worms are almost as loud as those of snapping shrimp, which produce sounds so powerful they can break small glass jars.

Yes, a late instar (older) caterpillar DOES have wings! They're simply hidden underneath its skin/cuticle. When a butterfly caterpillar pupates, its wings, antennae, and proboscis are clearly seen.
