Out doing another Big Meadow Search and I know I am supposed to be looking at plants but I was thrilled to find this Wasp Spider. If I wasn’t doing this project I wouldn’t be finding such gems and going to lots of random places

Rosebay Willowherb, Chamaenerion angustifolium (2 of 2). Look out for the leaf mines of the micro-moth, Mompha raschkiella. Initially the mine is filled with frass and often close to the midrib. Develops into a yellowish blotch with dispersed frass
Rosebay Willowherb, Chamaenerion angustifolium (1 of 2). Up to 150cm. Alternate, pointed, strap-shaped leaves. Mud-rib raised below. Pinkish-purple flowers up to 3cm across. Four unequally sized petals: upper 2 broader. Four long, narrow reddish sepals. Stigma 4-lobed

For #AquaticPlants for #wildflowerhour Fool’s-water-cress, Helosciadium nodiflorum
Woolly Alder Sawfly, Eriocampa ovata larva. Up to 2cm. Produces waxy secretion from epidermal glands to provide protection from predators presumably through mimicry of bird poo. In the final instar stage the waxy coating is lost and the larva is pale green. Feeds on Alder species

Hogweed, Heracleum sphondylium (3 of 3). Cheilosia illustrata hoverfly larvae mine stems and roots whilst adults often feed on the flowers. Adults will also feed on other umbellifers
Hogweed, Heracleum sphondylium (2 of 3). Larval food plant (along with Wild Parsnip) for the Parsnip Moth, Depressaria radiella. Larva forms a silk spinning amongst flowers and seeds
Another day and another new BMS site type for 2026: golf course rough. A glorious display of Harebell, Campanula rotundifolia
