Birch galls 2

Pictures from the Hainault website:

     

Aculus leionotus, a sort of uneven blister above, erineum beneath. Looks very like what I saw today.

    

Circular blister on both sides of the leaf. Anisostephus betulinus.

 

Silver birch hemispherical gall. Cecidophyopsis betulae.

     

The hairs of the erineum are described a reddish-brown. However I am seeing tufts of white in a similiar situation, could this be just as it develops? Aculus leionotus. I have also seen this, but both species cannot be A. leionotus.

Birch galls

Don't know what this refers to: Semudobia betulae A gall midge on Betula. Seed gall on Birch (Betula sp.).

Name changes 2004:

Betula	Eriophyes lissonotus	Aceria lissonota
Betula	Plemeliella betulicola	Resseliella betulicola
Betula	Massalongia rubra	M. ruber

p292       Betula: the upward bulge of the Aceria lissonota gall is sparsely hairy, and smooth in Aculus leionotus.

p293       Betula: delete Fig. 127 (left); Resseliella betulicola causes young leaves to crinkle and fold upwards, and thickens and folds upwards the edge of older leaves.

Betula pendula Ectodemia occultella 34 Lepidoptera found in the Wyre Forest

138 Lampronia fuscatella

(Tengström, 1848)

Wingspan 14-18 mm.

The adults of this species, unlike some of the otherLampronia species, are relatively plain in appearance.

The moth is quite local in Britain, occurring scarcely in a few widely scattered localities throughout. It flies in May and June, during the afternoon.

The larva is unusual in that it forms a swelling, or gall on a twig of birch (Betula), usually at a node, within which it feeds. The presence of reddish-brown frassaround the exit hole indicates a larva within.
