The upper side of the hindwings is dark brown colored with a red band in the submarginal area and small blue marks. The underside is also dark brown with various colors and shapes forming a complicated pattern.

Behavior

Males are highly territorial, chasing after Commas and Peacocks as well as other Red Admirals.  Red Admirals are one of the more intelligent butterfly species; they have the ability to habituate. Upon entering their territory an intruder is immediately investigated.

In the case of human intruders, a Red Admiral will circle around several times and will try to ascertain whether the person poses a threat. If he or she appears to be harmless the butterfly gets progressively braver.

At night or on cold overcast days, and during the winter months, they roost head-downwards on the trunks or lower branches of trees, where the dark underside of the wings provides them excellent camouflage.

Vanessa atalanta in Crete lives mainly in fields of medium-altitude, forest edges, gardens, orchards, ruderal areas, wet meadows.

The larva feeds on Urticaceae plants.

The butterfly flies in 2 generations per year.
