A listing of Lepidoptera for the Isles de Chausey 



The Chausey (Chaussey) Islands are here excluded from the survey of the British Channel Islands. 

 They are a compact cluster of French owned islands and rocks in the Golfe de St. Malo, midway between les 

 Minquiers and Granville on the French coast, being some 8 miles west of the Rock of Granville, and 9 miles 

 north of Cancale on the French coast. As noted earlier however, it is useful that some comparison of the fauna 

 between the Channel Islands and the Chausey group can be undertaken. In recent years French biologists have 

 carried out surveys of the fauna, which has included the Lepidoptera. To this purpose the following list 

 published by J.P. Quinette & N. Lepertel in 2000 (L'Argiope No. 27:35-38) is translated and reproduced, along 

 with their list of hostplants and status of the species concerned. It only covered the larger species and in the 

 main the microlepidoptera are omitted. The hostplants listed may be general for the species and not specifically 

 applying to Chausey, as will also be the status comments. The presence of some species, like Melanargia 

 galathea, Pseudoterpna coronillaria, Orgyia antiqua, and perhaps even Callistege mi, may indicate that the 

 Isles de Chausey could be one likely source for the spread of these rarities in the British Channel Islands. The 

 presence of Pyropteron chrysidiformis suggests that this species could be looked out for, especially in Jersey.
