Hi Steve
These are called processionary caterpillars, they are the
larvae of the moth Ochrogaster lunifer which is a very widespread
species, the big silken bags the caterpillars shelter in are a very common
sight in the arid zone, although they are also found near the coast. The name
processionary comes from their habit of moving from tree to tree in a line, each
produces a thread of silk which the one behind follows. I’ve seen this a
few times and it is always interesting to watch. An evil person could cause
them to go in circles by manipulating the leader to follow the last in line,
this would be very mean though.
Whatever you do, don't touch them or the bags they live
in. The hairs are toxic and can cause quite a bad reaction.
