Haliplus confinis Steph., 1828
|
17 
|
The 2.3 to 3.7 mm large crawling water beetle Haliplus confinis (family Haliplidae) is of short navicular shape. It is one of 30 representatives of the genus in Europe, of which 18 occur in Germany. The beetle lives in clean stagnant waters or quiet streams, where they feed on algae and plant parts. The stenotopic species is distributed from North and Central Europe to Siberia and has been recorded China lately. Like all Haliplidae H. confinis is a poor swimmer. Unlike the representatives of family Dytiscidae they use an alternate motion of legs and prefer rather to crawl on water plants than to swim, a behavior, which gave the family its vernacular name. The beetles are able to fly and reach suitable waters in this way. In Germany, the species is recorded from almost all Federal States but is regarded as vulnerable (RL 3). (CB)

Cylindera germanica L., 1758
|
19
|
The German Tiger beetle Cylindera germanica (family Carabidae) is one of only two species of the genus in Europe. It is known to occur in Europe and Asia. It prefers calcareous and semi-arid grassland, where the larvae develop in self-dug burrows in loamy or marly soil during two years. The populations of this xerophilous species have declined dramatically during the last decades and the beetle is now facing extinction in Germany (RL 1). Root cause for its decline is the loss of suitable habitats with sparse vegetation and open spots. These types of microhabitats are found in extensive agriculture, which has declined during the last decades, also on military training areas, which are rapidly overgrown by vegetation, once military training stops. Also eutrophication of calcareous grassland through immission of nitrogen compounds plays a role. (CB)

Platydema violaceum (F., 1790)
|
16
|
The darkling beetle Platydema violaceum (family Tenebrionidae) occurs from the southern part of North Europe over Central and South Europe and reaches the Caucasus in the East. In Germany, the stenotopic, mycetophilous species has been recorded throughout the country, although recent records are missing from Westphalia. The development takes place in Jew's ear (Auricularia auricula-judae), a saprophytic fungus mainly growing on elderberry (Sambucus), but also on various other deciduous trees, like beech (Fagus), birch (Betula) and elm (Ulmus). The beetle can be found throughout the year under the bark of deciduous trees, especially during the winter. While 50 years ago the species was very rare most regions in Germany, it has fortunately regained some territory over the recent decades. (TH)

Larinus beckeri Petri, 1907
|
20
|
The 6 to 8 mm large weevil Larinus beckeri (family Curculionidae) is one of seven quite similar species of the genus Larinus in Germany. It can be recognized by the rounded oval body shape and the relatively long and narrow snout. It ranges from Europe to Siberia, however, its exact range is not fully known. Larinus beckeri lives exclusively on knapweed species (Centaurea) in the lowlands, whereas the closely related sister species Larinus jaceae also uses various thistle species as host plant, preferably in the low mountain range. The larva develops and pupates in the flower. The beetles hatch starting July and hibernate. In Germany, Larinus beckeri is missing in the North and in the East and according to Rheinheimer/Hassler (2010) is regarded as endangered (RL 2). (CB)

Timarcha tenebricosa (F., 1775)
|
20
|
The 12 to 18 mm large bloody-nosed beetle Timarcha tenebricosa (family Chrysomelidae) is one of three species in the genus in Germany. Worldwide more than 100 species have been described from three subgenera, most of them in the Palearctic, a few in the Nearctic. The eurytopic, herbicolous Timarcha tenebricosa occurs in Southern and Central Europe. It prefers dry edges of forests and meadows, sunny meadows alongside rivers and creeks, dry slopes and vineyards. The oligophagous species develops on bedstraws (Galium). When disturbed, they exude a bright orange fluid from their mouth, hence their common name. The male exhibits enlarged tarsi, which allow it to cling firmly to the female when mating. In Germany, records are only known from the South and the West and the species is regarded as vulnerable (RL 3). (CB)

Leptura aurulenta (F., 1792)
|
28
|
The 13 to 18 mm large golden haired longhorn beetle Leptura aurulenta (family Cerambycidae) is one of five representatives of the genus in Germany. It can be potentially confused with its sister species Leptura quadrifasciata, which shows completely black legs. The stenotopic, thermophilous species occurs in Northwest Africa, South and Central Europe. It prefers sunny edges of forests and glades in the colline zone. Larval development takes place in trunks and rootstocks of dead deciduous trees, especially beech, but also oak, willow, poplar, alder, birch and chestnut. The adult beetles appear from June to August on umbellifers. They are quite agile in the sunlight and are able fliers. In Germany, the species is limited to the South and the West. It is regarded as endangered (RL 2). (CB)

Corticeus fasciatus F., 1790
|
15
|
The 3 to 3.2 mm large darkling beetle Corticeus fasciatus (family Tenebrionidae) is one of nine representatives of genus Corticeus currently recorded from Germany. The stenotopic, silvicolous species ranges from North Africa over South Europe to the southern part of North Europe and in the adjacent East Europe. The beetles prefer old deciduous forests, especially dry oak forests. They live on parts of oak trunk destitute of bark in in the galleries of anobiid beetles (Anobiidae) and timberworm beetles (Lymexylonidae). Formerly regarded as exclusively predaceous, they are meanwhile thought to be saprophagous and only facultative predators. The larval development presumably takes two years under the bark of the trees. In Germany, the species is recorded from most Federal States, but regarded as an Urwald relic species and endangered (RL 2). (CB)

Phrissotrichum rugicolle (Germ., 1817)
|
15
|
The 1.9 to 2.5 mm large Apionid weevil Phrissotrichum rugicolle (family Apionidae) is the only representative of the genus in Germany. It is easily distinguished from all other species of the family in our fauna by the bristle-like pubescence of the elytra. The stenotopic, xerothermophilous species is known to occur from France over Italy and Central Europe to Hungary. In Central Europe it lives only in habitats with a markedly warm microclimate, e.g. on warm slopes, sun-exposed banks, rocky and calcareous grassland on calcareous soil or gypsum. The oligophagous beetles develop on rock rose (Helianthemum) and needle sunrose (Fumana). In Germany, recent records are only known from the southern half of the country and Phrissotrichum rugicolle is regarded as very rare and endangered (RL 2). (CB)

Rhynchites bacchus (L., 1758)
|
27
|
The 4.2 to 6.8 mm large peach weevil Rhynchites bacchus (family Rhynchitidae) is one of six representatives of the genus in Germany. The thermophilous species occurs from North Africa over Europe to the Caucasus, Turkmenistan and North Iran. The beetle can be found in orchards, at waysides, in sunny river meadows and at the edges of forests. The oligophagous beetles live on trees of the Rosaceae family and are pests of economic significance in plum, apricot and apple. The female deposits its eggs from May to August in a chamber in the fruit. The larvae feed on the fruit pulp. After 4 to 8 weeks they leave the fruit and pupate in the ground. The new generation hatches in autumn and hibernates in the pupal chamber. In Germany, the species is mainly recorded from the southern half and ist not endangered. (CB)

Baris analis (Ol., 1790)
|
22
|
The 2 to 3.5 mm large weevil Baris analis (family Curculionidae) is among the smallest and rarest representatives of the 12 species of the genus Baris in Germany. It is easily recognized by the conspicuous red last third of the elytra. The species is known to occur in Europe from the British Isles to Greek, in the east it reaches Siberia. Baris analis lives wet grassland and at the edges of ponds and rivers on common fleabane (Pulicaria dysenterica). The larvae develop in the lower parts of the stem and in the roots. They pupate in the galleries and hibernate as imagines. The species is very local and rare. In Germany there are only a few records from Saxony-Anhalt and Baden and according to Rheinheimer/Hassler (2010) Baris analis is regarded as critically endangered (RL 1). (CB)

|
14
|
The 5.5 to 6.5 mm long Larger Black Flour Beetle Cynaeus angustus (family Tenebrionidae) is the only representative of the genus in Germany. The species originates from the Sonora desert in the southwest of the US and Mexico, respectively, where two more similar sister species are present. They live on debris of yucca and agave plants. Since the 1970s the species expanded quickly to the East as a pest in grain storage and on cotton gin trash. Since the mid of the 1990s first records of introduced specimen have been made from Germany and other European countries. The beetles can be found from June to September on chaff and waste of grains production and compost. In Germany, recent records are known from Baden, the Palatinate and Thuringia. The expansive species is not endangered. (CB)

Emus hirtus (L., 1758)
|
27
|
The 18 to 28 mm large rove beetle Emus hirtus (family Staphylinidae) is probably the most beautiful rove beetle in our fauna and the only representative of the genus in Germany. The eurytopic, thermophilous species occurs throughout Europe, in the East till western Central Asia. It prefers near-natural meadows, especially on warm and dry slopes, sandy sun-exposed pastures and dry edges of forests. Both beetles and larvae are predaceous and live on fresh dung of horses and cattle, where they prey on imagines and larvae of dipterans and other beetles. The hairs of the imagines are water- and dirt-repellent, hence the beetles can dwell on fresh cow dung without getting stained. In Germany, populations fluctuate considerably and often the species disappears for several years from certain locations. It is regarded as endangered (RL 2). (CB)

Platycerus caraboides (L., 1758)
|
23
|
The 10 to 14 mm large stag beetle Platycerus caraboides (family Lucanidae) is one of two species of the genus in Germany. The stenotopic, silvicolous species occurs from the southern part of North Europe over Central Europe to West Asia. It is missing in the North of the British Isles and North Scandinavia as well as in South Spain, Greece and large parts of the Balkan. Platycerus caraboides prefers warm beech forests in the lowlands and in the colline zone up to 750 m ASL. The similar sister species P. caprea however prefers cool and humid habitats in the montane and subalpine zone. The beetles feed on leaves and buds of deciduous trees. The larval development takes 3 years and takes place in white-rotten wood of various deciduous trees. In Germany, Platycerus caraboides is known from all regions and rather common. (CB)

Bruchus pisorum (L., 1758)
|
13
|
The 4 to 5 mm large pea weevil Bruchus pisorum (family Bruchidae) is one of 14 representatives of the genus in Germany and is today a cosmopolite. It is regarded as a major pest in pea cultivation. The female deposits its eggs on the outside of the pods. The larvae feed through the pod and develop inside the seed pod, where each larva digs itself into a pea seed where it later pupates. In this way, the beetle gets into storages. The infestation of the peas can be considerable. There are reports from the first world war, that pea soups from field kitchens where appreciated by the troops as particularly "tasty" due to the small pieces of "bacon" in them. Of course, these "soup additions" were the larvae of Bruchus pisorum. In Germany, there are recent records from the West and the East. (CB)

Aphodius luridus (F., 1775)
|
13
|
The 6 to 9 mm large dung beetle Aphodius luridus (family Scarabaeidae) is one of around 60 species in the genus currently occurring in Germany. The genus Aphodius is globally present and comprises more than 1000 species in numerous subgenera. Aphodius luridus is of palearctic distribution from North Africa over Europe to Eastern Siberia. Quite common in our fauna in the lowlands and the colline zone, Aphodius luridus can be found from March to early June on dung of various mammals, including sheep, goat, horse and especially cattle. The xerophilic species prefers sunny pastures, heathland, warm and dry slopes, especially on calcareous soil. Besides the typical yellow-black spotted specimen there are also all black specimen. In Germany, recent records are known from virtually all Federal States and the species is not endangered. (CB)

Bradybatus fallax Gerst., 1860
|
13
|
The 3.2 to 3.8 mm large weevil Bradybatus fallax (family Curculionidae) is one of the three species of the genus in Germany, besides B. kellneri and the rare B. creutzeri. The species is known to occur from Central Europe (in warm locations) to Russia in the East and to Italy in the South. Bradybatus fallax lives on field maple, Norway maple and especially on sycamore maple. The beetles dwell on the inflorescences and are therefore not easily found, as the maple trees are too high to allow easy access to the inflorescences. The larvae develop in the fruits of the host. The new generation hatches in late summer and hibernates dispersed in the habitat. Bradybatus fallax is recorded from most Federal States in Germany and is not regarded as endangered. It is most likely under-recorded due to the above-mentioned difficulties in finding it. (CB)
