Wood White (Leptidea sinapis) | |||||||||
| Description | |||||||||
| Wing span: 40-42 mm. The most delicate of the white butterflies, the Wood White has suffered due to changes in woodland management, particularly the reduction in coppicing. It always rests with its wings closed. The sexes are similar. Most of the populations in Britain are in the Midlands, central southern and south-west England, and south Wales. Most colonies breed on rides and clearings in woods, although a few large colonies occur on coastal undercliffs. | |||||||||

| Life Cycle | |||||||||
| There are usually two broods per year, with adults being on the wing from mid-May to July, and again in August. The pupa is the over-wintering stage. | |||||||||
| Larval Foodplants | |||||||||
| The primary larval foodplants are Common Bird's-foot Trefoil (Lotus corniculatus), Greater Bird's-foot Trefoil (Lotus pedunculatus), Bitter Vetch (Vicia ervilia), Tufted Vetch (Vicia cracca) and Meadow Vetchling (Lathyrus pratensis). | |||||||||
| Nectar Sources | |||||||||
