gregarious iris leaf miner
An abundant, southerly distributed species, associated
with
Iris foetidissima
; the larvae feed gregariously,
forming relatively large, opaque, greenish to yellowish
leaf mines. Damage also occurs on other cultivated
irises, including
Iris ochroleuca
and
I. spuria
. Pupation
takes place at the end of the mine in a stack of reddish-
brown or dark brown puparia, each puparium orientated
crosswise. Adults (wings 2.3-3.2 mm long) are mainly
black with just the fore knees yellow.

iris leaf miner
Conspicuous leaf mines formed by this widely
distributed species are often common on both wild and
cultivated yellow flag (
Iris pseudacorus
). Each mine is
broadly elongate with dark discrete patches of frass
clearly visible; the larva pupates in a black puparium
orientated lengthwise at the end of the mine. Adults
(wings 2.0-2.7 mm long) are mainly black, with bright
yellow knees.
