Note 2 — Chapter VIII · THE NEST-BUILDING ODYNERUS
Alexander Teixeira de Mattos translation
The second, O. alpestris, Sauss., is by trade a resin-worker. Possessing the same tool as her colleague the miner, but not the same skill, she does not dig herself a dwelling; she prefers to settle down in borrowed lodgings provided by an empty Snail-shell. The shells of Helix nemoralis, of H. aspersa,2 when very incompletely developed, and of Bulimulus radiatus are the only dwellings that I have known her to occupy and also the only ones that would serve her turn under the stone-heaps where, in company with Anthidium bellicosum, she performs her labours in July and August.
