Lasiommata megera (Linnaeus, 1767) Wall Brown
A hilltopping and territorial species, males may defend
their territories day after day; several may congregate
at hilltops. Generally uncommon and local, and scarcer
than L. maera, with which it is one of the earliest satyrids
to emerge in spring. Males perch or patrol along tracks
awaiting females, fly-glide with wings open in V shape, or
bask in wait with wings fully open. Males have a strong
diagonal sex brand on their upf, and begin courting head
to head, flapping their wings and dispersing androconial
scales and pheromones towards the female antennae.
Adults sometimes spend nights under overhanging
rocks. This is a cold resistant species; adults may survive
in -3°C, larvae in -8°C and pupae in ice (Lafranchis et

in pairs, on grasses growing in shady places, or ”in
clusters on roots or leaves of grasses” (Thomas &
Lewington, 2014: 241). The eggs are 1 mm in height,
spherical and greenish-white, changing to yellowish
towards eclosion. L1 hatches after one week and eats
the eggshell, is 2.5 mm long, yellow, hairy and with a
brown head, spotted black; body colour changes to green
when feeding commences. L5 is 25 mm long, green with
light green dorsal and subdorsal longitudinal lines and a
white lateral band, feeding in late afternoon and at night. Jordan, Wadi Dana, 600 m. 23.5.1998
The suspended pupa is 15 mm long, green (sometimes L. m. emilyssa Verity, 1919
brown) with 6-7 pairs of small white projections along the
back, hatches after 10-12 days in the summer but one
month in winter in temperatures of 9-12°C. Overwinters
as a larva, in warm areas it continues to grow slowly
throughout the winter (Lafranchis et al., 2015: 568-569).

partially metabolized by the males…and are converted into
dihydropyrrolizines which are used as pheromones during
courtship behaviour”. It was also suggested that the pure PA

against predators (Edgar et al., 1979; Smith, A., 2014) PA is
also transmitted by both males and females to the eggs. Males © Stav Talal
transfer it to the females by seminal infusion, and females
that collect PA themselves coat the eggs with PA protecting
it against predators (e.g. ants) and egg parasites (e.g. the
chalcidoid wasp, Trichogramma spp.), (Bezzerides et al.,
2004). On 29 Nov. 2021 DB observed several females sipping
