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

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

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
