Chapman's Green Hairstreak
Callophrys avisDistribution: N
Africa, SE and NW Iberian Peninsula and Mediterranean France. Usually near
the coast in Europe. Very local across its range.
Identification: The green underside is unique to the
Callophrys, of which there are two species in Europe. These two species are
very similar however and, I believe, rubi always flies wherever avis
is found. Please see the ID guide and photos below. Note: often the white stripe
is quoted as being strong in avis but this is certainly not reliable
enough to separate these two species.
Flight time: One generation. April in S Europe at sea
level. Said to fly into June at higher levels and in Morocco although I don't
have experience of this.
Habitat: Very dry scrubland with larval food plant the
Strawberry Tree, Arbutus unedo and early spring flowers.
Behaviour: Frequently visits flowers but spends most of
its time flying rapidly around the tops of its food plant Arbutus unedo.
Said to lay its eggs at the top of more mature plants. Never opens its wings
when at rest. When at rest on the leaves of trees or shrubs it is extremely
difficult to spot.
