Observational nature study based on Bird's-foot Trefoil growing in my lawn.
I am currently encouraging more flowers to grow in the short grass by less frequent mowing and raising the cut height. The seed heads resemble bird's feet, hence one of it's common names.
These plants are the larval food source for the Common Blue Butterfly, Polyommatus icarus. A tiny delicate butterfly now increasingly present in my garden. The upperwings vary from blue through brown and can be distinguished from the male Brown Argus by the placing of spots and the size of the abdomen.
