Platylesches neba
Hewitson, 1877
Although this species was described from Natal (
Hewitson 1877
) and
Evans (1937)
only recorded specimens from
South Africa
, it is now known also from
Namibia
,
Zambia
,
Zimbabwe
and
Mozambique
(
Pringle
et al
. 1994
,
Ackery
et al
. 1995
,
Heath
et al
. 2002
) and
north Kivu
,
Democratic Republic of Congo
(coll. Ducarme; T.B. Larsen pers. comm. 2012).. It is more widespread than
Pl. ayresii
, but also feeds on both
Parinari
spp.
We note however, a suggestion by M.C. Williams (pers. comm. 2012) that
Pl. neba
may represent a complex of forms or species, similar to that we have recognised above for
Pl. moritili
, with differing caterpillar forms.
Food plants
Pringle
et al.
(1994)
give the food plant as
Pa. curatellifolia
, whereas
Henning
et al
. (1997)
and
Woodhall (2005)
give it as
Pa. capensis
.
TCEC has collected it from
Pa. capensis
, and in captivity it feeds on
Pa. curatellifolia
.
Life history
The caterpillars of this species make tube shelters. TCEC found two caterpillar forms, one with a pale brown or reddish brown head (
Figure 79.1–4
), the other with a black head (
Figure 79.5–6
). Pupae have not been field collected and this species probably pupates in leaf litter, as suspected for other tube shelter makers.
The early stages documented by TCEC do not match those of
Pl. neba
described and illustrated with photographs by
Henning
et al
. (1997)
from
Pa. capensis
(note the legends for their photographs of the second and fifth instar caterpillars have been transposed). The first two instars are green with a black head, the third instar intermediate, and the fourth and fifth instars have the ‘head pale tan with creamy-white spots on front, outlined with brown’. The pupa, as they point out is ‘similar to that of
Pl. moritili
but with more pronounced dark lines along the wing cases and a blackish-brown head and thorax’. The first leaf shelter is a tube, but the second and third are made by pulling two, then three, leaves together. Pupation was in the final leaf shelter. This life history seems closest to that of
Pl. moritili
form
delta
treated above, and we suggest the life history illustrated by
Henning
et al
. (1997)
may actually represent a taxon that is part of the
Pl. moritili
complex.
