One of Europe's most widespread butterflies it is
found from the edge of the Sahara to northern Scotland and northern
Scandinavia to Greece. It occupies many habitats and is found from sea
level to high mountains (upto 3000m). Not surprisingly there are many
variations across this range. The constant feature that greatly helps
separate this species from several others is the presence of a black
spot in the underside forewing cell. This distinguishes it from the
otherwise very similar Chapman's Blue, A. thersites, and the
larger brighter Escher's Blue, A. escheri. In northern Greece the
Phalakron Blue, P. andronicus but this is so rare and local that
it is unlikely to be encountered without specific expeditions to look
for it. It is much larger than icarus. Confusion with other
species is unlikely.
The cell spot is absent in Common Blues as an
unusual but
apparently constant proportion of butterflies. I have heard in Switzerland that
the spot is absent in 7% of Common Blues. I don't remember seeing this in the UK so
perhaps it is rather rare there. However in Europe the Chapman's Blue is
extremely similar to the Common Blue but it always lacks this spot.
