Plants/ Trees

19/08/24   Aceria pseudoplatani agg. On the Sycamore leaves in Area 5 were Aceria pseudoplatani agg. These red, pimple-like bumps on the leaves of young sycamores are caused by tiny mites which overwinter in bark crevices and then emerge in spring to feed on the unfurling leaves. As they pierce individual cells to feed, the surrounding cells are stimulated to divide, enlarging and forming the prominent red galls. The mites lay eggs inside the galls from mid-May and several generations can occur over a season, finally exiting the leaves in autumn to overwinter in the bark. Although it disfigures a sycamore, it does no permanent damage to the tree.

15/08/24   Horse chestnut leaf miner Very visible along the Emm Brook at the moment is evidence of the Horse chestnut leaf miner Cameraria ohridella The horse chestnut leaf miner is the larvae of the moth Cameraria ohridella. The adult moths are tiny at about 4-5mm in length. They are a rich brown colour with bright white chevrons edged with black. In early summer, the adult female lays up to 180 eggs on newly opened leaves. The hatched larvae feed on the leaves. The larvae then pupate and can overwinter in the leaf litter until they emerge as adults in early spring to lay eggs on that year’s fresh leaves.

14/08/24   Knopper Gall Adjacent to the footpath by the Balancing pond in Area 4 are lots of Knopper Gall Andricus quercuscalicis on the Pendunculate Oak.The knopper gall wasp, Andricus quercuscalicis, is a tiny wasp that produces ridged outgrowths, or 'galls', on the acorns of our native Pedunculate Oak; forming in August they are sticky and red, later becoming woody and brown. A second generation then develops in the catkins of Turkey Oak.

05/08/24   Sycamore Tar Spot By the river in Area 6 while Balsam pulling by Emmbrook School was Sycamore Tar Spot Rhytisma acerinum . This is actually a fungus. The fungus overwinters on fallen leaves. Fresh spores are produced in Spring, these have a sticky coating. The spores attach themselves to the new leaves as they form. The fungus does no lasting harm to its host tree.
