Hippophaë, sea-buckthorn

Dichotomous table for leafminers

1a fleck mine; the larva mines from a case: Coleophora serratella

1b tentiform mine: Phyllonorycter corylifoliella

1c long, sometimes compact gallery, starting from a semiglobular shining egg shell => 2

1d small gallery or blotch, no visible egg shell => 3

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

2a slender, curving gallery, abruptly widened into a blotch; frass black: Stigmella hybnerella

2b gallery quickly and gradally widening, forming a secondary blotch; frass warm brown: Stigmella perpygmaeella

3a short gallery, often in a vein axil, almost completely filled with frass, followed by a long, clear, larval chamber; older lavae live free under a leaf: Bucculatrix bechsteinella

3b small irregular gallery or blotch with little frass; older larvae live between spun leaves => 4

4a mining larvae in June-July, greenish or yellowish with light brown head: Gelechia hippophaella

4b mining larvae in July-October, red-brown with blackish-brown head: Spilonota ocellana

* This family is closely related to the Rosacae, which explains the large number of typical Rosaceae-miners on sea-buckthorn.
