Carum caraway

(For a dichotomous table for galls on Carum by Hans Roskam click here)

Dichotomous table for leafminers

1a mine < 1 cm, full depth, very transparent; larvae with chitinised head; older larvae live free => 2

1b mine larger, upper- or lower-surface, greenish when lighted from behind; the larvae, maggots, mine all their life => 4

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

2a usually a number of mines together; they do not contain silk, remain therefore totally flat: Epermenia chaerophyllella

2b mines single; some silk is deposited inside, causing them to bulge somewhat => 3

3a larva: pinacula colourless (the bases of the setae themselves are black): Cnephasia incertana

3b pinacula black: Cnephasia asseclana

2a frass in isolated grains, scattered; larva with a frontal appendage, anterior spiraculum bifid: Phytomyza chaerophylli

2b frass grains close together, partly in pearl chains; larva without a frontal appendage, anterior spiraculum compact: Phytomyza mylini

Not included in the key: Depressaria daucella.
