Phyllonorycter rajella
Common Alder Midget

(Linnaeus, 1758)345 / 15.067

Morley’s Final Catalogue: Common about alders. Belstead, Ipswich, Sproughton, Bromeswell, bred (Whit.); Hacheston (Hkr); Leiston (Grey); Lowestoft (Bd). West Stow (Mly).

Recent Status: Not commonly recorded in Suffolk.

Life Style: The species may have up to three broods in a year and has been recorded from April to September. The larvae feed on Alnus species. They pupate in a cocoon in the larval habitation. The pupal stage passes the winter.

Identification: The moth is generally recognised by the broad basal streak. This can sometimes extend towards the dorsum giving the wing a pale base. The ground colour varies from light orange brown to grey but always with the marks edged and cilial line grey. There is a discrete terminal black spot. There are four costal and three dorsal marks. The first dorsal mark is oblique reaching along the dorsum. The third dorsal mark is very small.
The larvae create a small blister blotch on the underside between two veins and usually close to the mid vein. There is a prominent central crease in the lower epidermis. Leaf distortion is limited. There may be several mines per leaf. The cocoon incorporates frass. The pupal exuviae can assist identification. MBGBI Vol 2 should be consulted for this purpose. More Info

Mine: Either the leaf or a good photograph required
