Adult of a blastobasid moth,
Blastobasis
decolorella -
family Blastobasidae (x4).
A group of moderately small moths with promi-
nent labial palps and broadly elongate forewings;
base of antennae usually with a pronounced
tuft of hair (the pecten). Larvae with a well-
developed prothoracic plate and tortrix-like (see
family Tortricidae) but the anal prolegs with the
semicircle of crochets often broken into two
bands and the long subdorsal (SD) seta on the
eighth abdominal segment often placed more
dorsally than the spiracle
(Fig. 121).
The larvae
often feed within spun leaves, shoots or flower
heads.
EXAMPLES:
Depressariinae -
Agonopterix
nervosa
(carrot & parsnip flat-body moth),
Depressaria pastinacella
(parsnip moth);
Oecophorinae -
Endrosis sarcitrella
(white-
shouldered house moth).
narrow abdominal prolegs and small abdominal
spiracles; abdominal prolegs with relatively few
crochets (sometimes fewer than three), forming
a mesal penellipse
(Fig. 115e).
Larvae usually
feed within spun leaves or shoots.
EXAMPLES:
Anarsia lineatella {larva =
peach
twig borer),
Dichomeris marginella
(juniper
webber
moth),
Phthorimaea
operculella
(potato
moth),
Sitotroga
cerealella
(Angoumais grain moth).
20. Family BLASTOBASIDAE
A small group of small moths with elongate
wings
(Fig. 123).
Larvae
(Fig. 124)
tortrix-like
(see family Tortricidae) but with relatively small
abdominal spiracles; lateral (L) pinaculum on
prothorax placed below the spiracle
(Fig. 125);
subdorsal 1 (SDl) pinaculum on abdominal
segments 1-7 crescent-shaped
(Fig. 126).
Larvae
usually feed amongst debris and other dry
material.
19. Family GELECHIIDAE
(p. 210
et seq.)
Small moths with palps curved upwards; margin
of hindwing usually sinuous
(Fig. 122);
antennae
usually without a basal pecten. Larvae tortrix-
like (see family Tortricidae) but with relatively
