The Chinese endemic water beetle Amphizoa davidi Lucas, is a rare and endangered species belonging to the monotypic family Amphizoidae (Coleoptera: Adephaga). A study of the external and internal structures of A. davidi is here presented, by using X-ray phase contrast tomography and light microscopy. Morphological details and three dimensional (3D) structures of this species are provided: skele...

A review of insects collected from decomposing human remains in south-east Queensland yielded 32 species in three orders (Diptera, Coleoptera, Hymenoptera) and 11 families (Calliphoridae, Sarcophagidae, Muscidae, Phoridae, Sepsidae, Chironomidae, Dermestidae, Cleridae, Histeridae, Staphylinidae, Encyrtidae). There were 15 cases where remains were located indoors and five cases where remains wer...

In order to contribute to the knowledge of beetles (Coleoptera) of the mountainous region of Morocco, Talassemtane National Park (Western Rif, Chefchaouen district, Morocco) was surveyed. This is an exceptional protected area of the Mediterranean Intercontinental Biosphere Reserve (RIBM). The checklist was made using different traps combined with active periodical searches during 2013-2015. A t...

Members of the order Coleoptera are sometimes referred to as 'living jewels', in allusion to the strikingly diverse array of iridescence mechanisms and optical effects that have arisen in beetles. A number of novel and sophisticated reflectance mechanisms have been discovered in recent years, including three-dimensional photonic crystals and quasi-ordered coherent scattering arrays. However, th...

The diet and trophic groups of an assemblage of aquatic insects were studied in a tropical stream. Genera of the orders Ephemeroptera, Odonata, Plecoptera, Lepidoptera, and Hemiptera showed feeding specialization. Others, such as Trichoptera, Coleoptera, and Diptera, showed great diet variation with genera of different trophic groups. Seasonal variation of insect diet, evident only for some gen...

Hesperophanes pilosus Bodungen, 1908 – A new record of longhorn beetles (Coleoptera, Cerambycidae) for Iranian fauna with the first detection its host plant species

six species of rove beetles (coleoptera: staphylinidae), belonging to the genus philonthus stephens 1829, are reported for the first time from iran. they include philonthus juvenilis peyron, 1858, philonthus micans (gravenhorst, 1802), philonthus spinipes sharp, 1874, philonthus longicornis stephens 1832, philonthus viridipennis fauvel 1875, and philonthus wuesthoffi bernhauer 1939. all specime...

Abstract Intensive forestry is a threat to biodiversity, and therefore actions are made mitigate this loss. The are, however, designed based on available knowledge about the requirements of species, for saproxylic insects concerns mainly Coleoptera, while diverse but poorly known Hymenoptera has contributed less. In paper we asked whether substrate (divided as parasitoids non-parasitoids) simil...

Two new species of South American Glaresidae (Coleoptera: Scarabaeoidea) are described: Glaresis smithi Paulsen, new species from Argentina, and Glaresis mondacai Paulsen, new species from Chile and Peru. The species are compared to their closest congener, Glaresis fritzi Martínez et al., and a key is provided for the known South American species of the genus Glaresis Erichson.
