Hoshihananomia perlata (Sulz., 1776)
|
24 
|
In Germany, the 6.8 to 10 mm large tumbling flower beetle Hoshihananomia perlata (family Mordellidae) is the only representative of the genus, which comprises three species in Europe and more than 100 species in the tropic region, where it is quite speciose. Its distribution is discontinuous and ranges from South France to North Japan without Northern and Southeast Europe. The thermophilic beetle belongs to the Urwald relic species. The adult beetles can be found on blossoming herbs and shrubs as well as on dead wood. The larvae develop in dead wood of deciduous trees, mainly oak, beech and birch. In the sunshine, the beetles escape very swiftly when only slightly disturbed. In Germany, the species is regarded as endangered (RL 2). However, it has increased its range over the recent years.

Aphodius obliteratus Panz., 1823
|
19
|
The 4.5 to 7 mm large dung beetle Aphodius obliteratus (family Scarabaeidae) belongs to the speciose tribe Aphodiini, which comprises about 170 genera and more than 2000 species worldwide. From Germany, more than 60 species of the genus have been recorded. A. obliteratus is known to occur in Western, Central and Southern Europe and prefers forests. It can be distinguished from its similar sister species A. contaminatus by the missing long setae at the lateral margins of the pronotum. The beetles appear already early in spring, from February to April, and again in September and October. The development takes place in all kinds of dung, preferably of large herbivores. In Germany, the species is of more western distribution and is not too common. Aphodius obliterates is regarded as vulnerable (RL 3). (CB)

Platambus maculatus (L., 1758)
|
20
|
The 7 to 8.5 mm large diving beetle Platambus maculatus (family Dytiscidae) is the only representative of the genus Platambus in Germany, which is quite speciose in the Palearctic and to a lesser extent in the Nearctic. The stenotopic species ranges from Europe to the Caucasus and Western Siberia. It is rheophilous and lives in the stagnant water zone of slowly flowing rivers and creeks with rich vegetation as well as in the surf-zone of lakes. Often the gregarious beetles can be found at the lower side of driftwood and on the water vegetation. Beetles and larvae prey on other water insects. When disturbed they exude a defense secretion, which contains the sesquiterpene Platambin as main component (Schildknecht, 1975). In Germany, Platambus maculatus is recorded from all Federal States and is not endangered. (CB)

Lomechusa emarginata (Payk., 1789)
|
24
|
The 3.5 to 4.5 mm large rove beetle Lomechusa emarginata (family Staphylinidae) is the most common species of the three representatives of the genus in Germany. The myrmecophilous species is of Eurosiberian distribution. It lives on close relationship with ants: In autumn, the freshly hatched beetle leaves the nest of Formica fusca, waits a few days until the chitinous exoskeleton has hardened and the smell of F. fusca has worn off. It then hibernates in the nest of the European fire ant (Myrmica rubra). In spring it returns to the nest of Formica fusca and allows its larvae to be reared by the ants. The beetles can be found at the edges of forests and clearings, both in the ant nest but also on the lower vegetation around the nest or swarming. In Germany, L. emarginata is present in all Federal States and not endangered. (CB)

Cyrtosus ovalis (Cast., 1836)
|
19
|
The 3 to 4 mm large soft-winged flower beetle Cyrtosus ovalis (family Malachiidae) is the only representative of the genus in Germany. The first record for our fauna was made in North Baden in June 2010. In Europe the genus comprises eleven species with predominantly southern European distribution. Cyrtosus ovalis is known to occur in entire Italy. Furthermore records in Austria and Switzerland have been made. The stenotopic, thermophilous beetles prefer warm habitats, e.g. xerothermic shrubby heaths. The beetles can be found on flowers, where they feed on pollen. They are easily confused with representatives of genus Axinotarsus, but differ in coloration and the shape of the pronotum, which gets narrower towards the base. As a newcomer to the German fauna, Cyrtosus ovalis is not mentioned in the Red List. (CB)

Chrysobothris solieri Lap. Gory, 1837
|
23
|
The genus Chrysobothris belongs to the jewel beetles (family Buprestidae). There are four representatives of the genus in Germany. With 7 to 12 mm size, C. solieri is among the smaller species of the genus. The 2-year development cycle takes place in the wood of ailing or newly dead pine (Pinus), especially Scots Pine (Pinus sylvestris) in trunks and branches of diameters up to 15 cm. The infestation can be recognized by the brownish discoloration of the needles. At the end of the development the larvae hibernate in the puparium and pupate in the following year. The beetles are markedly thermophilous. The can be found during the warmest hours of the day on the host trees, where they escape swiftly when disturbed. In Germany, the species is regarded as vulnerable (RL 3). In the recent years, the species extended its range to the north. (KR)

Hoplia argentea (Poda, 1761)
|
21
|
The 9 to 11 mm large Hoplia argentea (family Scarabaeidae) is one of four species of the genus currently recorded in Germany. The species ranges from the southern parts of Central Europe to Southeast Europe and prefers montane regions. In Germany its occurrence is limited to the Alps and their foothills, the Bavarian Forest, the Swabian Jura and the Black Forest as well as the Lower Elbe region. Hoplia argentea is not endangered in Germany. It lives in open habitats with hedgerows, on meadows and at the edges of forests. The beetles feed on pollen, whereas their larvae live in the ground and feed on plant roots. The development cycle takes two years. The intense color of the beetles is caused by reflection of sunlight by their scales, the very same mechanism as in butterflies (interference color). (CB)

Trox perlatus (Goeze, 1777)
|
21
|
With a size of 7 to 10 mm Trox perlatus is among the largest representatives of the genus in Germany. In the past, the hide beetles (family Trogidae) were regarded as a subfamily of the family Scarabaeidae. Trox perlatus is a stenotopic and thermophilous species, which feeds on dry carrion, bones, fur and fur remains as well as hairballs. Occasionally the beetles can be found on excrements, mainly of dogs. Contrary to the other Central European representatives of the genus, it can be easily recognized by the shiny tubercles on the elytra and is unmistakable with any other Trox species in our domestic fauna. Trox perlatus is known to occur in Western and Southern Europe. In Germany the species is found only in the western part in warm and dry habitats and is generally regarded as rare and endangered (RL 2). (KR)

Bledius tricornis (Hbst., 1784)
|
26
|
The 5.5 to 7 mm large rove beetle Bledius tricornis (family Staphylinidae) is one of 40 representatives of the genus in Germany, which are not easily distinguished. The stenotopic species is known to occur in the southern Palearctic, from Southern Europe to the southern part of Northern Europe, Asia Minor, the Caucasus to South Siberia and China. The beetles are halotolerant, they can be found both on the coast and in the inland on sandy and loamy substrates. The front legs are of the fossorial type. The beetles dig burrow systems into the soil. When flushed with water, they come to the surface. Presumably they feed on algae. On warm days, the beetles swarm during dusk and are attracted to light sources. Bledius tricornis is recorded from virtually all Federal States, but is regarded as vulnerable (RL 3). (CB)

Anthicus bimaculatus (Ill., 1801)
|
23
|
The 3 to 3.5 mm large antlike flower beetle Anthicus bimaculatus (family Anthicidae) is one of five representatives of the genus in Germany. Worldwide, the genus Anthicus is present in all terrestrial ecozones. The distribution of the stenotopic, psammophilic Anthicus bimaculatus ranges from France over Germany, Poland and the Baltic states to Russia. Its yellow, brownish and black coloration serves as a good camouflage in its habitat, sandy edges of water bodies, both sea and inland fresh water, as well as sandy dunes, mostly at the roots of grasses and in detritus. During the day the beetles hide in the sandy substrate. At dusk the leave their hiding places in search for food. In Germany recent records are known from many Federal States, with the exception of the southeast. Anthicus bimaculatus is regarded as vulnerable (RL 3). (CB)

Niptus hololeucus (Fald., 1836)
|
25
|
The 4 to 4.5 mm large Niptus hololeucus (family Ptinidae) earned its vernacular name Golden Spider Beetle due to its shiny metallic color. The synanthropic species was introduced from Russia to England for the first time in 1833 and spread from there around the world. They can be found in old buildings, e.g. timber-framed houses and multi-story buildings with wooden beam ceilings. They live and develop mainly in straw, which was used as filling and insulation material. They are nocturnal and hide in cracks and crevices during the day. Often the tenants are not aware of their presence at all, until renovation work is carried out which liberates the beetles from the wooden ceilings. Although they are regarded as a mechanical pest, the damages are only minor and they should rather be seen as nuisance pest. The species is not endangered. (KR)
