A massive procession of caterpillars has paraded through Alice Springs.

The incredible collective was videoed by staff at a kangaroo sanctuary in the Northern Territory on Tuesday.

It was estimated to be more than 7m long.

The Kangaroo Sanctuary Alice Springs posted the video and this comment on Facebook: “They are famous for walking in processions. Each caterpillar when it walks leaves a thread of silk for the next one to follow them. Cool hey.”

Ridiculously Long Procession Caterpillar Spotted in Alice Springs, Australia

The Northern Territory government’s website warns against touching what are called processionary caterpillars. They are the larvae of the bag-shelter moth and the hairs leave human skin itchy for days.

But the processionary caterpillars are much more than just fascinating or irritating for the indigenous Arrernte people of Central Australia.

The length of the procession is an indicator of how harsh the coming cold season will be and whether there will be extreme frosts — the longer the procession, the more extreme the cold.

This helps people know when certain foods will be available, or unavailable, which is essential for survival if you’re living traditionally from the land.

Northern Territory Parks and Wildlife explained in a Facebook post: “For the Arrernte people of Central Australia such observations have been vital for surviving the harsh conditions of the Australian desert.

“Arandic* languages name two broad seasons: the ‘hot season’ and the ‘cold season’.

“For Arrernte people the length of the train of processionary caterpillars (iwepe, the juveniles* of the bag-shelter moth) is an indicator of the severity* of the forthcoming cold season.”

Some foods may only be available in the mild time between seasons, for instance, and in some years this mild time could be quite short.
