Immigration of insects into the british isles

ABSTRACT ABOUT a hundred years ago, it was gradually dawning on British entomologists that many of the butterflies in this country might be immigrants from abroad. Among the species first

suspected of this habit were the Clouded Yellow (Colias. croceus) and the Pale Clouded Yellow (C. hyale). It is curious that about the same time a more practical controversy was commencing

in the United States as to whether one of their most serious pests, the cotton worm (Alabama argillacea) was a permanent resident of that country, or not. To-day we know that not only these

early disputed species, but also many other Lepidoptera, dragonflies, and some members of other groups of insects, regularly migrate, and that in a number of cases these movements come to an

end in the British Isles, thus giving the insects in question the status of ‘immigrants’. Access through your institution Buy or subscribe This is a preview of subscription content, access
