Seasons: May

The Yellow slug lives up to its name - its yellow body is mottled with grey patches. Often found in gardens and damp places in houses, it can be considered a pest, but is an important nutrient recycler.

The White-lipped snail comes in different colour forms, but always has a white band around the opening of its shell. It prefers damp spots in wide range of habitats, from gardens to grasslands, woods to hedges.

The Brown-lipped snail comes in many colour forms, but usually has a brown band around the opening of its shell. It prefers damp spots in wide range of habitats, from gardens to grasslands, woods to hedges.

The Heath bumblebee is not only found on heathland, but also in gardens and parks. It nests in small colonies of less than 100 workers in all kinds of spots, such as old birds' nests, mossy beds and even roofs!

The Tree bumblebee is a new arrival to the UK. First recorded here in 2001, it is slowly spreading north. It prefers open woodland and garden habitats and can be found nesting in bird boxes and roof spaces.

One of our prettiest and smallest bumble bees, the early bumblebee has a bright orange tail and lemon-yellow bands on its body. It is very common and can be found in all kinds of habitats in early spring.

Unsurprisingly, the garden bumblebee can be found in the garden, buzzing around flowers like foxgloves, cowslips and red clover. It is quite a large, scruffy-looking bee, with a white tail. It nests in colonies.

The violet click beetle is a very rare beetle that lives in decaying wood, particularly common beech and ash. It gets its name from its habit of springing upwards with an audible click if it falls on its back. It is found at just three sites in the UK.

With yellow-and-black bands, the giant horntail looks like a large wasp, but is harmless to us. The female uses her long, stinger-like ovipositor to lay eggs in pine trees, where the larvae then develop.

With ginger hairs, dark banding and a cream tail, the Narcissus bulb fly looks like a bumble bee, but is harmless to us. This mimicry helps to protect it from predators while it searches for nectar in gardens.
