To make a meadow it takes a clover and a bee: the entomophilous flora of N.W. Europe and its insects Naturalis
Ellis, Willem N.; Ellis-Adam, Albertine C..
An analysis of the anthophilous fauna of N.W. Europe is presented, stressing the role plants play for insects. The study is based on some 29,000 relations between about 2,600 insect species and 1,300 plant species (569 genera). The data are derived from our database (“CrypTra”) of biotic relations between Cryptobiota and Tracheophyta, that is based on published sources. It is suggested that a ratio of 2 to 5 anthophilous insect species per entomophilous plant species is the rule in N.W. Europe, where other types of zoophily are virtually absent. A small minority of the plant species/genera play a disproportionally important role as hosts to flower visitors; many of these so-called cornucopian taxa belong to the commonest entomophilous plants in the region,...

New records, threatens and conservation status for Dichotomius schiffleri Vaz-de-Mello, Louzada & Gavino (Coleoptera: Scarabaeidae): an endangered dung beetle species from Brazilian atlantic forest ecosystems Neotropical Entomology
Vieira,L; Louzada,J; Vaz-de-Mello,FZ; Lopes,PP; Silva,FAB.
Dichotomius schiffleri Vaz-de-Mello et al is often cited as endemic to the preserved coastal sandy-dune vegetation (restinga) of Guriri Island, Espírito Santo state, and is included in the Brazilian List of Endangered Fauna as "critically endangered" (CR). However, we recorded its occurrence in twelve additional sites along the coasts of Espírito Santo, Bahia, Sergipe and Pernambuco. The geographic distribution of D. schiffleri is limited to the coastal Atlantic Forest domain, mainly in preserved restinga patches. We recommend that D. schiffleri remains in the List of Endangered species, but in the "endangered" (EN) category, according to the IUCN criteria.
