As its name suggests this is a butterfly of
southern Europe. It is widespread and often common. It has a lovely blue
sheen on the upperside that varies with the angle of light.
Superficially it is similar to the White Admiral, L. camilla
which shares the southern part of its range with reducta.
However, there are many differences. The hindwing basal area of reducta
is a bold silvery band and the ground colour is a rich red. In contrast camilla
has a pale grey basal area that is broken up by a warmer orange ground
colour. The upperside forewings also have an easy distinction - reducta
has a bold white cell spot, camilla may just have a shadow here.
It
flies in light woodland and along roadsides cutting through denser
forests. It glides gracefully with wings flat open between wing beats.
It can often be found resting at about head height on shrubs and trees
as if it is defending a territory. Indeed it might be but I don't recall
seeing them actively pursue other butterflies from these perches -
perhaps it is simply safer for this butterfly to sit in these locations.
