1	Forewing with shining golden metallic costal and dorsal spots 2

-	Forewing with one or two white or whitish dorsal spots 3


2 (1)	Larger species, 7.0-9.5mm. Forewing with cilia concolorous with wing, tips distinctly paler, but without clearly defined line; posterior costal spot broadly triangular *Antispila metallella*
	May and early June.
-	Smaller species, 5.0-7.5mm. Forewing with cilia darker than wing, tips pale yellowish grey beyond clearly defined line; posterior costal spot linear or acutely triangular *A. treitschkiella*
	June and July.

3 (1)	Forewing shining grey with small indistinct spot near base (sometimes obsolete) and a larger, somewhat better defined dorsal spot near tornus *Heliozela sericiella*
	6.0-8.0mm. Mid April to early June. Forewing without violet scales; dorsal spots whitish.
-	Forewing shining dark bronzy brown with indistinct spot near base (sometimes obsolete) and a larger clearly defined triangular dorsal spot near tornus *H. resplendella*
	5.0-7.0mm. Late May to late July. Forewing sometimes with scattered violet scales, particularly in apical area; dorsal spots pure white. The larvae of f. hammoniella Sorhagen do not feed on alder (Alnus spec.), but on birch (Betula spec.) Recently this form has been re-established as a separate species.
