The Wall Butterfly- I was excited, out in Derbyshire yesterday, to see my first Wall Butterfly since I was a child, until I learned they have declined by 86% since 1976. Research indicates global warming is the reason. It is thought that a whole generation is lost, especially in the South, by warmer weather which prompts the butterflies to hatch in autumn and fail to survive winter, instead of remaining as caterpillars/pupae through the winter, hatching in spring. The Wall is a gorgeously patterned amber and brown, with exquisite cryptic markings on the underwings (see photos). Typically, they rest on stony paths or walls, hence the name,
and fly up as you approach, re-settling a few feet ahead, as these did. Conditions: Cloudy with rain. Temperature: Max 20- Min 13C.
