The tree was located beside 1906870. Like wild cherry, bird cherry has a couple of small glands on the leaf-stalk, near the base of the leaf, but its long flower racemes (see https://www.geograph.org.uk/photo/1281185 ) are quite distinctive, and its white petals have finely-toothed edges. The red pustules visible here on the leaves are galls, caused by the gall mite species Phyllocoptes eupadi (Eriophyes padi), which is specific to bird cherry. They were up to about 2 mm high, with small projecting hairs, and were narrower at the point of attachment to the leaf. They tend to appear close to the midrib of the leaf. On the underside of the leaf, only small inconspicuous entrance holes were visible. The beetle at the bottom of the image is unrelated to the galls; for a closer look, see 1285818. For a a closer look at the same kind of galls, found in more or less the same spot, but better developed by about a month, see 1907303. Date: 3 May 2009. Source: From geograph.org.uk.
