Leafspot on cultivated Impatiens (probably I. pallida).
Tall, much-branched mullein growing in parkland. Seems to more or less match description of V. speciosum.
I think probably Phytocoris varipes.
Found in rough grass by pond.
Sawfly larva found on Alder by pond. Seems to more or less match a young larva of Cimbex connatus but I'm unsure.
I didn't see it uncurled so don't have exact length measurements but the widest part of the coiled up larvae was 1cm meaning total length was probably a little over 2cm long.
The two rows of black dot along the sides of the larva match descriptions but I can't find mention of the row of black dots along the dorsal edge.
