The Cream-spot Tiger is quite a common moth in both France and southern UK it is often attracted to lights and is on the wing in May and June.
The eggs are laid on groundsel, ragwort, chickweed, dead nettles and dock amongst other things, so the food plant is quite variable. The caterpillars hatch in July and are of the dark brown woolly type. They overwinter as caterpillars and then resume eating and growing in Spring. In May they spin a cocoon and turn into the pupae but only stay in this stage for a short time, hatching out in late May or June.
