ABSTRACT Although huge progress has been made over the past 200 years in identifying diversity of pollinators angiosperms and other plants, new discoveries continue to be each year, especially tropical areas fossil record. In this perspective article I address following questions: Just how diverse are what phylogenetic limits that diversity? Which groups animals, not currently known regularly engage with flowers, might found future? Can we predict, from record under‐researched parts world, which animal turn out future contain pollinators? also discuss why adding our knowledge plant–pollinator interactions is important, but stress an incomplete may a bad thing if it means remote, inaccessible relatively pristine world remain way.

In forensic entomology, research focused on sarcosaprophagous flies, but the beetles, as important "forensic indicator species" of late-stage PMI in cadaver decomposition, received less attention. To increase attention on, and use understanding of, beetles this paper presents a bibliometric analysis available relevant literature. The occurrence frequency beetle families species from succession studies, actual cases, experiments were calculated illustrated using graphs. As result, total 14 1077 associated with carcasses collected, Staphylinidae being most frequently recorded among families,

Abstract The orchid family is renowned for its enormous diversity in pollination biology. Many species use deception to attract pollinators, and the main strategy terrestrial orchids food deception. Food‐deceptive usually show a low number of pollinator visitations, making field observations pollinators difficult. In this study visual census, capture molecular analysis pollinaria found on caught insects allowed us obtain information composition pollinators. A total 321 were caught; most specimens hymenopterans ( Apis mellifera , Bombus ruderatus Eucera rufa ) coleopterans Tropinota hirta T. squalida ). identity which insect's body belonged was confirmed by analysis. Moreover, some individuals Billaea lata (Tachinidae, Diptera) captured photographed with their head. Two new important results emerged clearly work: dipteran, Anacamptis pyramidalis two beetles genus are Orchis italica . Our confirm that generalized food‐deceptive genera weak specificity.
