three dorsal streaks snowy-white, dark-margined towards the base of 
the wing; the apical black streak is rather short. Posterior wings 
grey, with paler cilia. 
Abundant in May and August. The larva mines the zpper side 
of the leaves of the nut; the large white blotches it makes are 
very conspicuous; when full-fed it causes the leaf to pucker very 
considerably, consequently, by the distortion of the leaf, the age 
of the larva may be known.

Head pale saffron. Face and palpi white. Antenne white, with 
faintly darker annulations. Hinder tarsi white, wnspotted. Anterior 
wings shining pale saffron-yellow, with a slender white basal streak 
dark-margined towards the costa, and with four costal and three dorsal 
streaks white, with dark margins (sometimes very faint) towards the 
base of the wing; the apical streak is ovate and blackish. Posterior 
wings pale grey, with paler cilia. 
Common in August. The larva mines the underside of the 
sloe-leaves in July. The variety? deflewella (which differs only 
in having the anterior wings irrorated with pale fuscous, and the 
basal streak deflected into the first dorsal streak,) is common 
among sloe-bushes in May; it is probably only the other brood 
of spinicolella.

Head pale saffron-yellow. Face and palpi white. Antenne white, 
annulated with very pale fuscous. Hinder tarsi entirely whitish, or 
spotted with very pale fuscous. Anterior wings pale saflron-yellow, 
with a straight, wmargined, white basal streak, and with four costal and 
three dorsal white streaks, which have distinct and broad dark margins 
towards the base of the wing; between the second pair of spots are 
frequently some dark scales on the disc; the black apical streak is 
rather oval. Posterior wings pale grey, with ochreous-grey cilia. 
Abundant in May and August. The larva mines the under- 
side of the beech-leaves in autumn and July.
