Zustand: New. 296, distribution maps, col photos. 244x175mm. PB. NEW. . This work covers 85 species of beetle in five main families, Hydraenidae, Elmidae, Heteroceridae, Scirtidae, Dryopidae, plus a small number of other wetland species in the suborder Polyphaga. This Atlas covers 85 species of water beetle and is complimentary to the previous two parts concerning the Hydradephaga and Hydrophiloidea. All three books are rather more than sets of maps, with as much effort made to identify gaps in the knowledge of their biology as to establish their distributions.The present recording scheme began in 1979, and over 550,000 records have been acquired through the activity of over 700 recorders, supported by the Biological Records Centre in Britain and the National Biodiversity Data Centre and CEDaR in Ireland. This section of the Atlas draws on over 79,000 records (Hydraenidae 20,000; Dryopidae 4,500; Elmidae 42,100; Heteroceridae 1,700; Scirtidae 10.700). [9781906698690].

Zustand: New. xii, 306, 98 distribution maps, 45 col text figs. 244x175mm. PB. NEW. . This work covers the hydrophiloid beetles in five families, the Helophoridae, Georissidae, Hydrochidae, Spercheidae and Hydrophilidae. 104 species are reviewed, all of them being recorded from Britain, 70 with certainty from Ireland, 52 from the Isle of Man, and 63 from the Channel Isles. 98 distribution maps are provided along with colour photographs of many sites.This Atlas is intended to be complementary to the 'Atlas of Predaceous Water Beetles or Hydradephaga' (2016). Both are rather more than just sets of distribution maps, with as much effort made to identify gaps in the knowledge as to discuss the basics of their identification, genetics and biology.The present recording scheme began in 1979, and over 149,000 records have been acquired through the activity of over 670 recorders, supported by the Biological Records Centre in Britain and the National Biodiversity Data Centre and CEDaR in Ireland.
