Small Heath

The Small Heath is commonly found throughout the U.K. in any grassland habitat, fields, roadside verges, woodland clearings etc. And normally spend a large part of their time well down in amongst the vegetation.

The male is smaller than the female and are quite similar in appearance but not the same.

The female's forewing undersides are a lighter orange in colour to that of the males which are slightly darker.

A female Small Heath 

Both sexes always land [roost, feeding etc.] with their wings closed. The upper side of the wings in both sexes are orange, again the females are slightly lighter than the males. There are two, sometimes three broods a year. They fly between late April and late June/early July and, between late July/late September and, if there is a third brood, October. They overwinter as a caterpillar in stages/instars.
