The sail grasshopper is a green grasshopper with long antennae and characteristically curved hindwings. It lives in tall grass and herbaceous vegetation, where it finds food and shelter. Warm, sunny areas with varied vegetation can provide good habitats.

The great spotted woodpecker is a black, white, and red woodpecker that finds insects in tree bark and dead wood. It carves out nest holes in trees, which can later be used by other birds and animals. It can therefore be called an “ecosystem engineer.” Old trees and dead wood are therefore important to the woodpecker.

The Dwarf Blue is Denmark’s smallest butterfly and spends its entire life among and around stands of round-leaved vetch, on which the caterpillars feed. The round-leaved vetch most often grows in gravel pits, newly graded road embankments, coastal slopes prone to landslides, dune areas, and other disturbed sites, where the dwarf blue butterfly can be found in large numbers.

The fox is an adaptable predator that also lives in urban areas. Its diet includes small rodents, insects, fruit, and carrion. Green spaces and hiding places allow it to find food and move around the city.

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 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 woodland helleborine is an orchid that often grows in forests, thickets, and shady green areas. It can also be found in urban environments where soil and light conditions are suitable. Gentle care and protection of its habitats are important for the plant.

The mourning cloak is usually a rare butterfly in Denmark, but since the 1970s it has been seen more frequently in the country. It is, however, widespread throughout the rest of the Nordic region, particularly in Sweden and Finland. Its flight season extends from late July into August. It inhabits forest clearings and forest edges with willow and birch trees.

The house redstart thrives in open urban environments with buildings, rocks, and bare surfaces. It catches insects from vantage points and builds its nest in crevices and cavities. It is well adapted to industrial areas and other rugged urban environments.

The pipistrelle is one of Denmark’s smallest bat species. It is found in large numbers throughout most of Denmark and is a protected species. Its fur is predominantly reddish-brown or dark brown on the upper side, while it is slightly lighter or grayish on the underside. The ears and ear flaps are short and rounded. The pipistrelle primarily hunts mosquitoes, flies, and butterflies. Hunting begins after sunset, when the bats often hunt together in small groups.

The hare lives primarily in open areas with grass, herbs, and other low vegetation. It is a herbivore and uses tall grass and thickets for cover. A combination of open areas and denser vegetation can provide it with both food and shelter.

The jay is a rather shy but intelligent corvid. It is most often seen flying among the treetops in deciduous forests, where it spends most of its time. Occasionally, however, jays are spotted in open country and at feeding stations. Jays live year-round in a small area. In years when acorns are plentiful, large flocks of jays may arrive in Denmark from the north to spend the winter.

The redstart is widespread throughout Denmark, where it inhabits mainly old deciduous forests, parks, and gardens with old trees that have hollows. The redstart is most common in Eastern Jutland and on the islands. The redstart is a migratory bird that winters in sub-Saharan Africa or around the Nile in East Africa.

The protected brown bat hibernates from October through April in hollow trees or attics, where it can find some shelter. If it gets very cold, the bats wake up slightly so they don’t freeze to death. The brown bat has long, narrow wings. It can reach a wingspan of 35–40 cm. It feeds on insects that it catches in flight.

Common bittercress is a yellow-flowering plant that grows in dry, sunny areas, along roadsides, and in other open habitats. The flowers attract various insects in search of nectar and pollen.
