A male Orange-tip butterfly was flying around in my garden near Stockliegh Pomeroy on 28 March. According to the Natures Calendar website, which monitors spring events, this is early for this species. With the sunny weather this past week, a lot of spring events have been happening. For example, young oak leaves are already unfolding here. This gives rise to worries about a dislocation in timing between the arrival of migrant songbirds and availability of food for their nestlings. Oak trees provide abundant moth caterpillars, which feed on their young leaves, and are taken by nesting songbirds for their young.
