Yes, that means letting them eat your plants.
It is June as I write this, and now is the time of the yearly emergence of Scarlet Tiger Moths (Callimorpha dominula). Each time I glance out of the window, I can see them fluttering above the cascading ivy of the wall. These beautiful insects defy all of our assumptions about moths: They are incredibly colourful, they fly in the daytime, and the adult moths feed on the nectar of flowers.
Holly Blues (Celastrina argiolus) are one of twenty species from the Lycaenidae family that can be found in the UK. It's upper wings are sky-blue and it can be distinguished from the similar Common Blue (Polyommatus icarus) by the underside of the wings, which are silvery-grey with small black spots in the Holly Blue. Its caterpillars feed on Ivy and Dogwood in our garden, but Holly is also a very important host plant.
The Scarlet Tiger (Callimorpha dominula) is one of the strongest presences in the garden. Its bright hairy caterpillars emerge from hibernation in early spring and feed on the Comfrey and Blackberry. Unlike most caterpillars that try to be inconspicuous, camouflaging themselves or hiding on the underside of leaves, the Scarlet Tigers are so confident in their distastefulness that they sit out boldly out right out in the open.
The Brown Hairstreak is a nationally scarce butterfly whose caterpillars feed on the young leaves of Blackthorn and occasionally other plum species. The adult butterflies feed on the sugary secretions of aphids, called 'honeydew' as well as the nectar of Blackberry blossoms. in our garden, we recorded them laying laid their eggs on the branches of a young wild plum tree.
Everyone has heard by now that bee populations are in trouble. Many people assume this means we should build more honeybee hives, but in reality it is wild bees that really need our help. Of the 20,000+ species of bee on Earth, around 90% of them are solitary, meaning they do not live in colonies or have queens or workers.
Of the solitary bee species that you are most likely to encounter in the UK can be grouped into two broad categories: Ground-nesting bees, and Aerial-nesting bees. Among the ground-nesters are 65 species of Mining Bee: Three of these nest in my garden lawn.
