Xylocopa
Carpenter bees (Xylocopa spp.) are solitary bees of up to 2.5 cm closely related to honey bees and bumblebees. They have a worldwide distribution favoring warmer climates. Carpenter bee stings are rare. However, a fatal case after a Xylocopa tranquebarica sting has been reported in Sri Lanka.12 Three allergens have been isolated in Xylocopa appendiculata ; a PLA2 similar to that of bumblebees and honey bees, and two melittin-like peptides.13 Currently, none of the allergens is WHO/IUIS (World Health Organization and International Union of Immunological Societies) accredited.
