jecting maxillary palps. Larvae of various forms:
prothoracic plate sometimes ill-defined (sub-
family Argyresthiinae); abdominal prolegs
with crochets often arranged in several con-
centric circles (i.e. multiserial) (e.g. subfamily
Yponomeutinae) (see later in Fig. 276) or with a
circle of small crochets surrounding a penellipse
of larger crochets (e.g. subfamily Plutellinae)
(Fig. 115d).
Larvae of many species feed within
plant buds, fruits or shoots; some are gregarious
and web-inhabiting.
EXAMPLES:
Acrolepiinae -
Acrolepiopsis
assectella
(leek moth); Argyresthiinae -
Argyresthia pruniella
(cherry fruit moth);
Plutellinae -
Plutella xylostella
(diamond-back
moth); Yponomeutinae -
Yponomeuta
spp.
(small ermine moths).

17. Family COLEOPHORIDAE
(casebearer moths)
(p. 209)
Small moths with narrow, pointed wings
(Fig.
119);
antennae directed forwards when in re-
pose. Young larvae are leaf miners but later
instars inhabit portable cases, formed from silk
and leaf fragments; cases often cigar-shaped or
pistol-shaped
(Fig. 120);
crochets on the abdomi-
nal prolegs often scattered and much reduced in
number but, typically, at least those on each anal
clasper arranged in a uniserial transverse band.
EXAMPLES:
Coleophora anatipennella
(cherry
pistol casebearer moth),
Coleophora laricella
16. Family EPERMENIIDAE
(p. 208
et seq.)
A
small group of moths, structurally similar
to members of the family Yponomeutidae but
with stiff bristles on the hind tibiae and hind
tarsi
(Fig. 118).
The larvae feed mainly on
Umbelliferae, at first mining the leaves but later
inhabiting webs.
EXAMPLE:
Epermenia aequidentellus
(a leaf
miner on carrot).
