idas (Linnaeus, 1761) [non-British] Brown Blue 



Guernsey - [attributed to Ansted & Latham, 1 862, however, this is incorrect, the name is not listed in any edition 

 of this publication and is only mentioned by Long, 1970. It is possible that Long may have mixed the 

 name with aegon which is a synonym of argus.The species idas is confusingly mentioned in 1990, 

 Emmet & Heath (eds) The butterflies of Great Britain and Ireland 7(1): 18 as an earlier alternative 

 name for agestis and :148 as a junior synonym of argus; in 1996, Karsholt & Razowski (eds), The 

 Lepidoptera of Europe :208 lists idas as a good species of Plebeius [sic] Kluk; in 1997, Leraut, Liste 

 systematique et synonymique des Lepidopteres de France, Belgique et Corse (2nd Ed.)] :186 also lists 

 idas as a good species of Plebejus Kluk]. Long stated that identification was probably due to confusion 

 with Plebejus argus, continuing to state that idas is distributed over the whole of France and that the 

 occurrence of an odd specimen in the Channel Islands is not impossible; R. Long, 1970(21 ):249 

 {named as Narrow- bordered Silver-studded Blue} [species remains unconfirmed].
