    Foodplant and Larval Feeding Signs

    Hypericum perforatum (perforate st john’s-wort), see plant distribution map, Hypericum hirsutum (hairy st john’s-wort).

    In Europe also found on Hypericum maculatum (imperforate st john’s-wort).

    Larval feeding on the terminal leaves of the young plant cause them to droop slightly and then wither. The larva then mines the stem from the tip completing its development as a pupa in a case constructed from part of a leaf which drops to the ground.

    Habitat

    Rough ground, dry meadows, grassland, open woods, roadsides, downland and stream sides.

    Finding the Moth

    Larva: feeding on the terminal leaves of the young plant cause them to droop slightly and then wither. The larva then mines the stem from the tip completing its development as a pupa in a case constructed from part of a leaf which drops to the ground in June.

    Adult: can sometimes be disturbed from around the foodplant; flies from early evening and comes to light.

    Similar Species

    Care should be taken when identifying this species particularly if worn.

    A few similarly-sized Gelechiid species (see below) have this combination of dark forewing and whitish yellow tornal and costal spots. The colouration of the labial palps are one of the more useful features to aid determination. Outside the main flight period, Eulamprotes immaculatella will need to be considered and dissection may be necessary.

    nb - labial palp (lp) segment one is very short (difficult to see) and tucked back below the eye, segment two is broader and extends forward to a position in front of the base of the face, segment three is thin and needle-like curving up in front of the face.

    Eulamprotes atrella - lp segments 1, 2 and 3 obviously ochreous with the lower edge in segment 3 narrowly fuscous (blackish brown). Forewing has apical quarter with a purple sheen.

    Eulamprotes immaculatella - lp segment 1 dark fuscous and segment 2 greyish white above and on sides, dark fuscous below. Slightly smaller species with diffuse or absent (particularly if worn) paler forewing markings.

    Aproaerema anthyllidella - lp segment 1 purplish-fuscous, segment 2 variable in extent of buffish-white and purplish-fuscous and segment 3 buffish-white with outer edge purplish fuscous. The forewing often has yellowish ochreous scales in the fold (lower central part of the forewing at one-third). This species has a dark cilia line obvious in fresh specimens, absent in Eulamprotes spp.

    Syncopacma sangiella - lp segment 1 purplish-fuscous, segment 2 inner surface buffish white, outer surface has a variable mix of darker and lighter scales and segment 3 inner surface buffish white, outer surface purplish fuscous. Generally a larger moth.

    Syncopacma albipalpella (rare) - lp segment 2 has white ring at apex. A small species.

    The above and another May record are reported as having been confirmed by dissection. They are however exceptionally early dates and may reflect some unusual climatic/ecological circumstance at the breeding site.
