Dingy Skipper - Erynnis tages 

The Dingy Skipper is locally distributed throughout Britain and Ireland. Adults usually fly from early May to the end of June but they can begin to emerge as early as mid-April in warm springs. Eggs are laid singly on young leaves of the foodplants and females choose the longest shoots of large plants growing in sheltered situations. The larvae hide in tents formed by spinning the leaves of the foodplant together and feed through the summer months. When fully grown, each larva spins more leaves together to form a hibernaculum in which to spend the winter. Pupation occurs the following spring in the hibernaculum, without further feeding.

Foodplants of the Dingy Skipper are mainly Common Bird's-foot-trefoil Lotus corniculatus, Horeshoe Vetch Hippocrepis comosa and Greater Bird's-foot-Trefoil L. pedunculatus may also be used.

 Marsh Fritillary - Euphydras aurinia

The wings of this beautiful butterfly are brightly patterned, with more heavily marked races being found in Scotland and Ireland. The larvae spin conspicuous webs that can be recorded quite easily in late summer. Eggs are laid in large batches of up to 350 eggs. Larvae are gregarious and spin a protective web that becomes conspicuous by the end of August. The nests, which are easy to count, occur in intermediate length swards (8-25 cm), although shorter swards (5-15 cm) can be used where foodplants are very abundant (e.g. on downland). The larvae overwinter in a small web close to the ground, usually within a dense grass tussock. They emerge in early spring and can be seen in clusters of up to 150 small black larvae when basking in the weak sunshine. They eventually become solitary and can disperse widely over the breeding habitat. Pupae are formed low down in grassy vegetation, either deep within grass tussocks or amongst dead leaves.
