)OLJKW SHULRG ‘early February to mid-April in up to three
broods; each brood only flies for a very short period’
(Pittaway, 1979: 96); variable, between early February
and early April in a rainy year, but only mid to late April in M. persea
#
a dry year (Pittaway 1981: 31); February to May (Larsen, M.a. acentria
1983: 434); February – April (Walker & Pittaway, 1987:
94). Numbers and flight period fluctuate each year, M. acentria ssp. ?
depending on the weather. In some dry years no adults © DUBI Benyamini © DUBI Benyamini © DUBI Benyamini
are produced (Larsen, 1983: 434; Pittaway; 1985: 191).

/LIH KLVWRU\ egg laying was never observed (Pittaway, M. a. arabica
pers. comm. to DB) but aggregation of larvae strongly
suggest that it does not differ from the northern M. a. DGXOW
acentria, i.e. eggs are laid in batches on the LHP low HJJ 1 2 3 4 5 6 7 8 9 10 11 12

down near the ground. Young larvae are gregarious,
later spreading over the hostplant where “...some areas
being completely stripped of leaves, flowers, as well as
seedpods” (Pittaway, 1979: 96). The life cycle of M. a.
arabica matches the seasonality of its sole LHP; in spring © Dubi Benyamini © Dubi Benyamini © Dubi Benyamini
when blue ‘carpets’ of the LHP cover the biotope arabica 4
manages to rapidly produce two generations. At this time
its greatest enemy is the domestic goat which, having
exhausted the less aromatic plants, moves on to nibble Holotype
the LHP. However, by this period the final brood small (L2
– L3) larvae have already finished their growth and are
hiding in their summer diapause at the base of the LHP.
Pittaway (1985: 191) did not record any adults following 7
a ‘very dry winter and spring’ of 1984, suggesting that
the diapausing L3 larvae did not emerge from their
diapause web and ‘skipped an unfavourable year’. Such © Dubi Benyamini © Dubi Benyamini
long-term larval summer diapause in Nymphalidae / M. a. arabica
Melitainae is yet unknown to DB (except Melitaea spp. in
high latitudes where larval overwintering of cold period
may last more than a year). The pupa (12-15 mm long)
is typical Melitaea, in being pearly white with small black
and tan specks. These are normally formed at the base
of the LHP, although many of the first generation hang
fully exposed on the upper stems, where they form up in
a week (Pittaway, 1979: 96). [Both the L5 larva and pupa
are illustrated in monochrome in Pittaway (1979: plate
vii), and in color in Walker & Pittaway (1987: 94).]
