Dichotomous table for leafminers

1a corridor of 5 mm at most, followed by a circular excision of ca. 5 mm diameter: Incurvaria pectinea

1b blotch or tentiform mine => 2

1c galls, etc. => Tables for all parasites per species

2a snow-white, under-surface rounded blotch, often containing several larvae or pupae: Macrosaccus robiniella

2b yellowish or greyish, upper-surface, rounded blotch with one larva or pupa: Chrysaster ostensackenella

2c whitish upper-surface blotch, overlying the midrib, rather narrow with lobed extensions: Parectopa robiniella

2d The larva of Obolodiplosis robiniae lives in a cavity in the leaf that resembles a grey tentiform mine. However, the mine does not contain silk.

Acacia was introduced in the middle of the 17th century from eastern North America (Weeda ao, 1987a) and, like in most exotics, its mining fauna is extremely poor; as late as in 2008 the first native miner was observed on it (I. pectinea).

Not included in the key: Liriomyza congesta.
