Dasytes gonocerus is a species of soft wing flower beetles belonging to the family Melyridae. [1]
This species has an extensive and discontinuous presence in part of Europe (Andorra, Bosnia and Herzegovina, Bulgaria, Croatia, Switzerland, France, Italy and Spain). [2]
It mainly occurs at high altitude in mountainous meadows of central Spain, of the Cantabrian mountain, on the Pyrenees, on the Massif Central, in the western part of the Alps, in part of the Apennines and on several summits of the Balkans. [3]
Dasytes gonocerus can reach a body length of about 4.5–5.5 mm (0.18–0.22 in). [3] These small black beetles have long erect black pubescence over the entire surface of the elytra and pronotum.
This species is very similar to Dasytes alpigradus and Dasytes lombardus . The three species are morphologically very close and only the males can be differentiated with certainty after examination of their reproductive organs (aedeagus). [4]
Adults can be found from July to September. These beetles feed on pollen and can be found especially on yellow Asteraceae. [3]
The whirligig beetles are water beetles, comprising the family Gyrinidae that usually swim on the surface of the water if undisturbed, though they swim underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. The family includes some 700 extant species worldwide, in 15 genera, plus a few fossil species. Most species are very similar in general appearance, though they vary in size from perhaps 3 mm to 18 mm in length. They tend to be flattened and rounded in cross section, in plain view as seen from above, and in longitudinal section. In fact their shape is a good first approximation to an ellipsoid, with legs and other appendages fitting closely into a streamlined surface. Whirligig beetles belong to the beetle suborder Adephaga, which also includes ground beetles and diving beetles.
Amphizoa is a genus of aquatic beetles in the suborder Adephaga, placed in its own monogeneric family, Amphizoidae. There are five known species of Amphizoa, three in western North America and two in the eastern Palearctic. They are sometimes referred to by the common name troutstream beetles.
Cleroidea is a small superfamily of beetles containing over 10,000 species. Most of the members of the group are somewhat slender, often with fairly soft, flexible elytra, and typically hairy or scaly.
Cleridae are a family of beetles of the superfamily Cleroidea. They are commonly known as checkered beetles. The family Cleridae has a worldwide distribution, and a variety of habitats and feeding preferences.
Melyridae are a family of beetles of the superfamily Cleroidea.
Tenebroides mauritanicus, commonly known as the cadelle, is a species of beetle in the family Trogossitidae. It is a common cosmopolitan pest in storehouses and granaries.
Valgus hemipterus is a smallish species of scarab beetle found in the Northern Hemisphere.
Gyrinus natator, the common whirligig beetle, is a species of beetle native to the Palearctic realm, including much of Europe. Its range extends northwards as far as Norway, Finland, and the Saint Petersburg area of Russia. It is an aquatic beetle and moves rapidly around on the surface or swims underwater in still or slow-moving fresh water.
Phycosecidae is a family of beetles in the superfamily Cleroidea., containing the single genus Phycosecis found in Australia, New Caledonia, New Zealand and Vanuatu. The beetles are small, about 1.5–3.5 mm in length. They live in sandy coastal areas, and are saprophagous, feeding on faeces, carrion, and dead arthropods during the daytime.
Prionoceridae is a small family of beetles, in the suborder Polyphaga. They form a group within the cleroid beetles and were formerly treated as a subfamily (Prionocerinae) within the family Melyridae. Very little is known of their life history but most species are pollen feeders as adults and occur in large numbers during spring or the host flowering season. Larvae are predatory or feed on decomposing wood.
Brachyta interrogationis is the species of the Lepturinae subfamily in long-horned beetle family. This species was described in 1758 by Carl Linnaeus in the 10th edition of Systema Naturae under the name Leptura interrogationis.
Pachyta quadrimaculata is a species of the Lepturinae subfamily in long-horned beetle family.
Clytus rhamni is a species of round-necked longhorns belonging to the family Cerambycidae, subfamily Cerambycinae.
Clytra quadripunctata is a species of leaf beetle in the subfamily Cryptocephalinae. Its common name is Four spotted leaf beetle.
Tarsostenus is a genus of checkered beetles in the family Cleridae. It includes the cosmopolitan species T. univittatus.
Thanerocleridae is a family of beetles belonging to the superfamily Cleroidea. It was formerly considered a subfamily of Cleridae, but was recently elevated to the rank of family. The family has 36 living species in 10 genera, which are found globally, mostly in low-latitude tropical regions, though the genus Zenodosus is found in temperate North America. Thaneroclerid species are likely all predatory both in adult and larval stages. They target small fungus and wood associated beetles, and are generally found in places where such beetles are likely to be found, typically tree associated habitats such as under bark, though some species occur in other locations such as termite nests.
Aplocnemus alpestris is a species of soft-winged flower beetles belonging to the family Rhadalidae.
Dasytes tristiculus is a species of beetles belonging to the family Melyridae.
Dasytes plumbeus is a species of beetle that is native to the Paleartic, but has also been introduced to North America.
Lygistopterus sanguineus is a species of net-winged beetle in the family Lycidae.
