OLIVER E. PRYS-JONES, ERLING OLAFSSON AND KRISTJAN KRISTJANSSON
Contrary to traditional thinking, Bombus jonel/us (Kirby) is not the only bumble bee in Iceland. An ecological study of the species in 1979 revealed the presence of B. hortorum (L.), B. iucorum (L.) and B. jonellus. B. hortorum was found in the Reykjavik area in habitats supporting introduced flowers, and was unrepresented prior to 1959 in collections dating back to 1913. B. hortorum has probably become established since the 1950s, and B. iucorum may also be a recent· introduction.
