NORWICH/WHITLINGHAM: Interesting oomycete and some willow feeders

Late August 2021

Never one to pass up on the chance of a walk, after dropping Cathy & Rose off at the Cathedral for an event I carried on up to St James' Hill and had a stop around the bit of Mousehold Heath in front of the prison. On the way up I noticed some powdery distorted plants, and with a bit of research came to the conclusion it was Lesser Swine-cress, twisted and coated with an Oomycete called Perofascia lepidii. Possibly new to Norfolk.


Later in the day I called in at Whitlingham, where amongst other things I saw some Giant Willow Aphids and some sawfly larvae, tentatively Euura pavida, also feeding on willow.
