Dichotomous table for leafminers

1a brown tentiform mine: Calybites phasianipennella

1b tiny corridor or blotch, < 1 cm, usually several in a leaf: Hypera rumicis

1c corridor, may widen into a blotch => 2

1d blotch, without an evident initial corridor => 8

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

2a corridor epidermal, silvery: Calybites phasianipennella (young mine)

2b corridor full depth => 3

3a corridor hardly widening => 4

3b corridor appreciably widened in the end => 5

4a the corridor makes about 5 circles or semicircles around the egg: Enteucha acetosae

4b corridor not spiraled: Adscita statices

5a larva slender, very active when disturbed, with light brown head => 6

5b larva compact, sluggish, with a black head => 7

6a gallery contains but little frass: Teleiopsis diffinis

6b gallery with much frass: Teleiopsis rosalbella

7a imago (beetle): metallic green: Mantura chrysanthemi

7b imago steel blue: Mantura obtusata

8a blotch rather small, with broad extensions, usually at the leaf margin; larva with chitinised head; at start of the mine no egg shells visible: Mantura rustica

8b blotch large, eventually huge; larvae maggots; at the start of the mine, at the leaf underside, a group of elongated egg shells => 9

9a larva: mandible with some fine teeth (rare): Pegomya bicolor

9b larva: mandible with two large and some fine teeth (rare): Pegomya vanduzeei

9b mandible with ± 3 large teeth (very common): Pegomya solennis

Not included in the key: Cnephasia asseclana, incertana; Liriomyza trifolii; Monochroa rebeli, rumicetella, sepicolella; Neofriseria peliella; Orthochaetes setiger; Pegomya haemorrhoum; Teleiopsis lunariella.
