Plant Parasites of Europe

leafminers, galls and fungi



Incl. Laburnocytisus.

For a discussion of the biology and the parasitoids of Laburnum miners see Askew (1968a).

Dichotomous table for leafminers

1a fleck mine, larve mines from a case => 2

1b fleck mine, larva mines while living free between tqo sandwiched leaves: Mirificarma cytisella

1c tentiform mine => 3

1d corridor or blotch => 4

1e gallen etc => Tabellen voor alle parasieten per soort

2a anal section of the case strongly curved downwards: Coleophora colutella

2b anal section straigt or only weakly curved: Coleophora trifariella

3a mine strongly contracted, larva solitary: Phyllonorycter staintoniella

3b mine flat, several larvae or cocoons in a mine: Macrosaccus robiniella

4a mine practically without frass; initially stellate, on the midrib, eventually a large blotch: Micrurapteryx kollariella

4b mine does contain frass, not beginning on the midrib => 5

5a a corridor, not or very little widening, not following the leaf margin: Phytomyza cytisi

5b narrow short corridor, followed by a small blotch: Leucoptera laburnella (youth mine)

5c eventually a secondary blotch => 6

6a frass in broad concentric arches; larva with chitinised head; mine not positioned along the leaf margin: Leucoptera laburnella

6b frass not in arches; larva a maggot; mine along the leaf margin: Agromyza demeijereri
