“What The Hell Are You?”

Well this ugly fella is a lot less menacing and a lot less smaller. Known as the Pale Tussock or the Dasychira Pudibunda, this is a moth native to Denmark. The bright yellow caterpillars are covered in patches of spiky hair that resemble porcupine quills, and along the centre of their back is another row of hair tufts, one on each segment of its body, culminating in a large black or brown spine at the rear end.
From a distance the caterpillar looks like a brightly-coloured baby bottle brush, but up close where you can see those double rows of gnashers, it’s not quite so cuddly. Every now and then, Pale Tussock populations will explode, resulting in a carpet of these caterpillars covering the trees. In 1988, a wave of Pale Tussocks demolished 20 hectares of beech forest in Denmark.
