Northern Eggar caterpillar
Came across this fully gown Northern Eggar caterpillar on the moors this morning.
The Northern Eggar is an upland form of the Oak Eggar (Lasiocampa quercus). The Oak Eggar generally has a one year life cycle whilst the Northern Eggar has a two year cycle, seeing such a large caterpillar at this time of year appears to be more consistent with a one year cycle. The split between Oak and Northern Eggars is complex I think.
