At present we have a lot of Processionary Caterpillars moving around in a line, that can be quite long (measure one at 5m with over 100 individuals) from one feeding tree (usually an acacia) to another but we found one procession off track heading into the garage.
There was also a little bit of confusion when a break in the line caused a build-up to occur with no leader to head them out.
They are the larvae of the Processionary Caterpillar Moth Orhrogaster lunifer (photos from an earlier post below)
