In terms of environment, what is important for these beetles is the presence of the plant dock (Rumex) which they eat. The adult beetles seldom fly but they move considerable distances on foot. They are active from March to October. The overwintering beetles from last year first appear in late March/early April after terminating diapause. | | |
| | Lagria hirta | | Lagria hirta is a species in the order beetles (Coleoptera), the suborder Polyphaga, the infraorder Cucujiformia (synonym Chrysomeliformia), the superfamily Tenebrionoidea (synonym Heteromera), the family darkling beetles, also called darkening beetles (Tenebrionidae, formerly known as Lagriidae), the subfamily long-jointed beetles (Lagriinae), the tribe Lagriini, and the genus Lagria. Lagria hirta are widespread and in the temperate zones of Europe and Asia, common. This species is not regarded as endangered. | | |
| | | Anthrenus pimpinellae | | Anthrenus pimpinellae belong to the genus Anthrenus, in the order beetles (Coleoptera), the suborder Polyphaga (water, rove, scarab, longhorn, leaf and snout beetles), the infraorder Bostrichiformia, the superfamily Bostrichoidea (carpet, powder-post and death-watch beetles), the family skin beetles (Dermestidae), the subfamily Megatominae (synonym Anthreninae) and the tribe Anthrenini. This species has several subspecies such as: Anthrenus pimpinellae pimpinellae, Anthrenus pimpinellae incertus, Anthrenus pimpinellae isabellinus and Anthrenus ... | | |
| | Soldier beetles | | The soldier beetles (Cantharidae; synonym Chauliognathidae), also known as leatherwings, are a family in the order beetles (Coleoptera), the suborder Polyphaga and the superfamily Elateroidea. From the 4000 species which are found worldwide, around 100 are common in Central Europe. Some examples of species worldwide are : common red soldier beetle (Rhagonycha fulva), Rh... | | |
| | Water scavenger beetles | | Water scavenger beetles (Hydrophilidae) is a family in the order beetles (Coleoptera), the infraorder Staphyliniformia and the superfamily Hydrophyloidea. From the 2300 species which exist worldwide, around 109 are found in Germany. Among these (as in those found in Germany) species are: Hydrous piceus, Hydrochara carabo... | | |
| | Alder leaf beetle | | The alder leaf beetle (Agelastica alni) belongs to the genus Agelastica, in the order beetles (Coleoptera), the suborder Polyphagan beetles (Polyphaga), the infraorder Cucujiformia, the superfamily Chrysomeloidea, the family leaf beetles (Chrysomelidae) and in the subfamily Galerucinae. Scientific synonyms for Agelastica alni are: Adimonia violacea, Cryptocephalus violacea and Chrysomela alni.

| After 5 to 14 days the larvae hatch. At the end of the 3rd larval stage they are about 11 mm in length and pupate. The larvae of alder leaf beetles are first olive, later cyan and shortly before pupating bluish in colour. They have 2 rows of very hairy warts. The larvae, like the adult beetles, feed on the leaves of the grey or speckled alder (Alnus incana), hornbeam (Carpinus), birch (Betula) and hazel (Corylus). They feed, initally in groups and later alone, by scraping the surface off the leaves from the underside, leaving only the ...
...s from the lower surface by scraping them off. The development of the larvae is complete in 3 weeks (June/July). They pupate in oval spaces in the earth just beneath the surface of the soil, where they remain for 8 to 11 days. In August the beetles of the new generation leave their pupae. | | |
| | Fairy-ring longhorn beetle | | The fairy-ring longhorn beetle (Pseudovadonia livida) of the order beetles (Coleoptera), suborder Polyphaga, infraorder Cucujiformia and superfamily Chrysomeloidea belongs to the family of longhorn beetles (Cerambycidae). Here (in the subfamily Lepturinae and tribe Lepturini) it belongs to the genus Pseudovadonia. Scientific synonyms for fairy-ring longhorn beetles include: Leptura livida , Vadonia livida , Anoplodera livida and Pseudalosterna livida. | | |
| | Mature larvae are able to secrete a substance which drives away their competitors ,especially adult beetles of the same species, from the leaves of the forage plants. At the end of the third larval stage, the larvae dig down into the soil to a depth of about 2cm and pupate. After 6-9 days the adult beetles hatch from their pupae. They have a flight radius of about 10 metres. In late autumn they begin eating intensively and continue this over a period of a few days in preparation for the winter. When the beetles have consumed enough nutrients, they bury themselves in the soil close to the food plant at a depth of several centimetres and remain there until late March or early April. Among the natural enemies of Gastrophysa viridula are insectivores and... | | |
| | Checkered beetles | | Checkered beetles (Cleridae) are a family in the order beetles (Coleoptera), the suborder Polyphaga, the infraorder Cucujiformia and the superfamily Cleroidea. Subfamilies of the checkered beetle are: Clerinae, Epiphloeinae, Enopliinae, Hydnocerinae, Korynetinae, Tarsosteninae, Thaneroclerinae and Tillina. Ther... | | |
