Abstract
Two aphids belonging to the genus Illinoia native of the Nearctic Region (USA) are recorded from France and other Western European countries. I. morrisoni (Swain) is known on numerous conifers, frequent on Cupressaceae and particularly on Cupressus arizonica, on which it has been observed in France. Unlike the former, I. liriodendri (Monell) is monophagous on the tuliptree, Liriodendron tulipifera (Magnoliaceae), which is an urban tree and a forest tree of interest in the area. Some identification characters of the species are illustrated and elements concerning their biology in the new area of distribution are discussed.
