Speckled Wood
Pararge aegeria
Distribution: N Africa, most of Europe except northern Scandinavia and
parts of Scotland. There are two subspecies distinguishable by the orange or
cream colour of the upperside spotting, although there are intermediate forms
and overlaps in many places so I wonder if these true subspecies:
ssp aegeria. The "southern" orange subspecies
predominates in the south west Europe (including Spain, Italy, N
Africa).
ssp. tircis. The "northern" cream subspecies is found in northern
and eastern Europe (including N France, central Europe, Scandinavia,
Balkans and Greece). Interestingly, the various Greek islands harbour
one or other of the two subspecies, apparently even when close
geographically.
Identification: Similar species exist on the Canary and Madeiran
islands - I've never been there although reports are that these species are much
larger and darker on the wing. It also resembles the Wall,
Lasiommata megera but this has solid orange
areas on both sides of the fw, rather than the spots of the present species.
Flight time: Just about all year! Often one of the first butterflies
(apart from hibernating species) to fly so dates are highly dependant on
location (latitude and altitude). They are continuously brooded so they can be
found in all the warmer months. I've found them on 1st January in Tunisia and as
late as the end of October in the UK. Populations may drop between broods but
usually some representatives can be found. This is one of the few butterflies
that can hibernate in more than one form - either larval or pupal.
Habitat: Associated with trees and scrub, it is rarely found in open
grassland. From cool mountain or northern positions to very hot dry places in
the south. Larvae feed on various grasses.
Behaviour: Flies particularly in the dappled shade of woodland paths
or edges. In scrubby areas it will skulk around the lower parts of the taller
bushes or even large rocks or outcrops. In woodland the males will often sit in
a beam of sunlight on a prominent leaf or twig and defend a territory from any
intruders. Usually he will return to the same spot. In more open places there is
less of a premium on the "best" twig/ leaf in the sunshine but territorial
behaviour is still displayed.
Additional notes: I've found this butterfly just about everywhere I've
visited. It can be very common or in low numbers. I am convinced that its
territorial habits in shady places make this butterfly sensitive to approach.
