Icaricia icarioides,[1] or Boisduval's blue, is a butterfly of the family Lycaenidae found in North America. This butterfly has 25 recognized subspecies.[2]
This species has been classified in at least four different genera since it was named by Jean Baptiste Boisduval in 1852. It started out in Lycaena, was transferred to Icaricia by Nabokov (Hodges et al., 1983), moved to Aricia by Bálint and Johnson (1997), merged with some other genera in the supergenus Plebejus by Gorbunov (2001), which was accepted by Opler & Warren (2003) and Pelham's Catalogue (as of 2012);[2] however, Lamas (2004) among others use Aricia. More recently, it was moved back to the genus Icaricia, which was reinstated as a result of molecular studies (Vila et al., 2011; Talavera et al., 2013). Synonymy, subgenera, and subspecies vary considerably depending on the author.
Their range extends throughout the western US and Canada from southern Saskatchewan to British Columbia.[3] Its habitats include dunes, mountains, meadows, streams, and sage-lands. It is also found in open areas or openings in woods near its larval host.[4]
Larvae feed on species of lupines (Lupinus).[3] Adults feed on nectar from flowers of Eriogonum species and other composites.[4]
Wingspan: 21 to 32 mm.[3]

Icaricia icarioides est une espèce nord-américaine de lépidoptères de la famille des Lycaenidae et de la sous-famille des Polyommatinae.
L'imago d’Icaricia icarioides est un petit papillon qui présente un dimorphisme sexuel : le dessus a une coloration bleu violet bordée de brun chez le mâle, et brune suffusée de bleu chez la femelle. Le revers est gris clair orné, de rangées de points noirs cerclés de blanc.

Œuf.
La chenille est rouge violacé ou verte, avec des bandes violacées sur le dos et des bandes diagonales blanches sur les côtés.
L'espèce Icaricia icarioides a été décrite par l'entomologiste français Jean-Baptiste Alphonse Dechauffour de Boisduval en 1852, sous le nom initial de Lycaena icarioides[1].
Elle a souvent été placée dans des genres différents en fonction des sources, notamment dans les genres Plebejus et Aricia. Son placement actuel dans le genre Icaricia a été confirmé par de récentes études de phylogénétique moléculaire[2].
De nombreuses sous-espèces ont été décrites[1] :
Les imagos volent d'avril à septembre suivant le biotope, en deux générations au Canada[3].
L'espèce hiverne au stade de chenille.
Les plantes-hôtes sont des lupins (Lupinus)[4].
Icaricia icarioides est répandu dans la moitié ouest des États-Unis, dans le Sud-Ouest du Canada et en Basse-Californie (Nord-Ouest du Mexique). L'espèce est commune et fréquente un large éventail de biotopes, comme les clairières, dunes côtières, landes et prairies de montagne[5],[4].
La sous-espèce californienne missionensis, en danger d'extinction, fait l'objet de mesures de protection[4].
