Continuing on from the last post, the caterpillars are leaving their nest to over-winter underground and pupate . Caterpillars leave the nest at dawn, forming a procession that can be several meters long.
Some caterpillars split off from the main procession, forming smaller processions. Moths will start emerging from the underground pupae from October until approximately end of November.
These caterpillars appear pink because we have applied pink fluorescent dust on them to improve visibility at night, video of the caterpillars feeding at night can be viewed here.
