The common swift spends almost its entire life in the air, where it catches flying insects. It breeds in cavities in buildings and is therefore dependent on safe nesting sites. Nesting boxes, built-in nesting cavities, and a rich insect population can help this species in urban areas.

The red-furred earth bee is a solitary bee with distinctive reddish-brown fur. It digs burrows in the ground, where the female constructs cells for her offspring. Sunny patches of ground and flowering plants provide it with both nesting sites and food.

The garden bumblebee has a long tongue, which makes it particularly well-suited to visiting flowers with deep corollas, and it is an important pollinator of these flowers. It needs flowers throughout the season and suitable nesting sites.

The house bumblebee is a compact bumblebee with a brownish thorax and a light-colored abdomen. It often builds its nest above ground in cavities, such as in birdhouses and buildings. It pollinates many different flowers and thrives in green urban environments with varied vegetation.

The dusky hawk-moth is one of the most common hawk-moths in Denmark. It is found in forest clearings, forest edges, and open country. It is particularly recognizable by its very bright red color. The caterpillar is green, brown, or black with distinct, large eye spots. At the rear of its body, it has a curved “horn.” If the caterpillar is startled, it can retract its head into its thorax, causing it to swell up. The eye spots become large, and it is likely capable of scaring off some birds of prey.

The Cape Moth is a common nocturnal moth that is active after dark. The larvae feed on a wide variety of herbs and low-growing plants, while the adult moths may visit flowers to feed on nectar. A diverse plant community provides food throughout several life stages.

The tailed hawk-moth is a rare butterfly in Denmark. It visits the country in the summer and can appear in large numbers in some years. The swallowtail is found in areas with bindweed and wildflowers. This butterfly is seen on slopes, in fields, meadows, and gardens. It is often mistaken for a hummingbird, as it hovers completely still in the air while sipping nectar with its long proboscis.
