Now at the beginning of Middle Spring, when pollen covers the pussy willows, then honeysuckle, mock orange, privet, wild multiflora roses, lilac, black raspberry and coralberry leaves break out from their buds, and that is a signal for cornus mas and lungwort to flower and for mourning cloak butterflies and cabbage moths to navigate the warming days past equinox. A little later come the question-mark and tortoise-shell butterflies and then the white-spotted skippers.
