Unearthed two large larvae about 50mm white with large brown head and several sets of legs at head end. Are these something I should treasure
No, cutworms . They will eat the roots of whatever plant they are under.
Hi kathie. They are chafer grubs and will destroy the roots of grass and other plants in the garden. Pest I'm afraid.
let the birds get at them,
Did not think something that appealing could be nice yes nutcutlet the birds have them, there is no accounting to taste ! Thanks to all for valuable info Kathie
