Crab Apple Tree in Blossom Spring 2016
‘Oak Apples’ April 2019
Oak apples are caused by chemicals injected by the larva of a gall wasp belonging to the Cynipidae family. The adult female wasp lays a single egg in the developing leaf buds on the oak tree. The wasp larvae feed on the gall tissue resulting from their secretions, which modify the oak bud into the gall, a structure that protects the developing larvae until they undergo metamorphosis into adults.
‘Oak Apples’ August 2019
The same Oak apples from April 2019, once the larvae have undergone metamorphosis and the adults left the ‘apple’.
