For a bit of light relief.
I wonder what species these were and would thousands of people turn up if they occurred today!

"In the month of June 1881, quite a sensation was created in the district by the extraordinary spread of caterpillars on Pendle Hill and Nick of Pendle. Swarms were also at the village of Chipping a few miles away and hens gorged themselves to such an extent that they died of repletion.

Thousands of people visited the neighbourhood to inspect these swarms.

The caterpillars had a soft cylindrical body and varied in length from three quarters of an inch to an inch and a half. They had three pairs of short, horny, thorn-like legs in the front and four pairs of false feet, or "clingers". Their colour was a dark, shiny olive, relieved with two or three thin well defined, yellow stripes along the whole length of the upper part of the body. The under portion was of a uniform lighter shade of colour. 

Naturalists differed in their designation. One was of the opinion that it was the Silver Y Moth (Plusia gamma); another contended that it was the larvae of the Antler or Grass Moth (Charoeas graminis). 

The keeper of the moor said the caterpillars were making such a fearful havoc with the herbage that the farmers were contemplating making a trench along the bottom of the moor to prevent them getting into the lowlands.

A youth gathered some in a box and exhibited them at the market in Burnley, charging a penny for the sight of them. He did fairly well until a gang of reckless young fellows burst into the penny show and scattered the insects far and wide."
