Non-native invasive insects have major impacts on ecosystem function, agricultural production, and human health. To predict the geographical distributions of these species, correlative ecological niche models are typically used. Such methods rely on assumptions of niche conservatism, although there is increasing evidence that many species undergo niche shifts during invasions. However, knowledge regarding niche conservatism and functional traits related to invasion dynamics remain incipient for many insect groups, in particular to Coleoptera – largest clade of Animalia. We compiled a novel database of 54 globally invasive beetle species, examined niche dynamics across this group, and whether factors such as human influence index, climate, feeding habits, body size and niche breadth may be associated with degree of invasion.
