The first North American record for Elachertus scutellatus , a parasitoid of Calpodes ethlius Stoll, occurred August 1999, in Florida.

The African bee therefore provides an excellent opportunity to examine the factors that influence invasion success. We provide a synthesis of recent research on the African bee, concentrating on its abil...
