Distribution
I will forever associate
this species
with childhood summers and still remember the day I first found them at
the end of my garden, when I was 8 years old. They positively smell of
sunshine and grass and shady trees as spring is opening into summer.
Happily, large skippers are common all over Europe (though much more
sparsely distributed in southern Iberia than the map above suggests) so
memories are easy to come by. They have a preference for humid areas,
often by water, and may be seen perching on bracken and bramble leaves
in quite dense woodland.
The only species a large skipper might be confused with is the
silver-spotted skipper, which is rather similar from the upperside,
though the silver-spotted skipper is more contrasting. The males of
both have a conspicuous sex brand in the middle of the forewing.
Beneath, however, the two species are quite different. Large skippers
have somewhat obscure yellow spots on an orange ground, tinged with
grey on the hindwing. In contrast, silver-spotted skippers sport
silver-white spots on a deep green ground and are quite unmistakable.
Eggs are laid on various species of grass and the caterpillars, like
those of many skippers, feed in a tube formed by rolling a blade of
grass and securing it with silk. The caterpillars hibernate when quite
mature, so are able to feed up, pupate and emerge relatively early in
the year compared to other golden skippers, typically appearing in May
in hotter regions (like the Rhône Valley of Switzerland) or June
further north, and flying until August. According to Tolman the species
is bivoltine in Spain.
