This is a scarce species, which has recently been expanding its range. The adults fly amongst the trees but descend to take nectar or moisture.
It over-winters as an egg. The larval food plant is Honeysuckle.
The adult seen on the morning of 2 July 2011 in Hadleigh Railway Walk had landed on a piece of damp ground, on the old track-bed.
I saw three White Admirals in Fermyn Woods on the afternoon of 26 July 2012. They were on the first green cross ride off the hard track in from the entrance opposite the glider field. They swooped down from the trees one at a time and flew back and forth, low down along the ride, settling for short periods on the ground or on low foliage.
