Some Cattleya are more resistant than others.
Although damage from cattleya flies may have been noticed in Hawaii earlier, Swezey first recorded the pest in Honolulu in 1914. Cattleya fly is native to the tropical areas of the New World. Probably eradicated in Hawaii soon after it was discovered, it was re-introduced in 1948. The damage to orchid plants is extensive and is mainly done by the feeding larvae. Oviposition by the female wasp and subsequent early feeding of the larvae cause dormant bulbs to actively grow.
