Abstract
Campylomorphus homalisinus has been found on Mt. Lesima (Northern Apennines) and it is the first record for the Lombardy region. Campylomorphus homalisinus is a rare orophilous species: it has a discontinuous chorology that may have been caused by glaciers dynamics during the Pleistocene era. Little is known about the ecology of the species. This record and the expert-based investigation we performed determined that Campylomorphus homalisinus inhabits shrublands and grasslands, but may also occur in the forests. This survey includes the only record of Campylomorphus homalisinus foraging on flowers, a behavior that is not rare in the family Elateridae. We hypothesize that adults integrate their diet with flower resources according to a generalist strategy.
Highlights
Coleopterans play an important role in pollination (Faegri and van der Pijl 1979) being among the most frequent flower visitors (Gómez et al 2013)
Species ranges and especially their dynamic are so important that the International Union for Conservation of Nature (IUCN 2001) includes two criteria related to species biogeography in the process of assessing the threatened status of species: Extent Of Occurrence (EOO) and Area Of Occupancy (AOO)
We have three questions about Campylomorphus homalisinus: 1) Has it ever been collected in the Lombardy region (Italy)? 2) What are its global distribution and altitudinal range? 3) What is currently known about its ecology?
Summary
Coleopterans play an important role in pollination (Faegri and van der Pijl 1979) being among the most frequent flower visitors (Gómez et al 2013). One of the less studied species is Campylomorphus homalisinus (Illiger, 1807). Some historic works highlight the presence of the species in Italy, France and Iberian Peninsula (Chevrolat 1840), without giving details. In the case of Mt. Cenis (Deville 1935), the presence of the species has not been confirmed by recent saproxylic insects’ surveys (SAPROX, Inventaire des coléoptères saproxyliques de France métropolitaine, available on inpn.mnhn.fr). Cenis (Deville 1935), the presence of the species has not been confirmed by recent saproxylic insects’ surveys (SAPROX, Inventaire des coléoptères saproxyliques de France métropolitaine, available on inpn.mnhn.fr) Such cases might be explained by incorrect identification (Platia, in verbis). It is really important to update the distribution of Campylomorphus homalisinus: to improve current knowledge about its ecology and biogeographic history. We have three questions about Campylomorphus homalisinus: 1) Has it ever been collected in the Lombardy region (Italy)? 2) What are its global distribution and altitudinal range? 3) What is currently known about its ecology?
