Spanish fly is a 2 cm long metallic green beetle of Meloidae family (Blister Beetles). It can be found primarily in warm climates in Europe and Asia. This beetle feeds on leaves of ash, privet and others deciduous trees. Spanish fly has a very complicated development, going through several larval stages which parasitize on solitary bees.
The male of Spanish fly produces liquid which contains a strong poison cantharidin. Cantharidin has a significant aphrodisiac effect, which is why it was used during the Middle Ages as an ingredient in various love potions. Since antiquity, powder from these beetles has been used by various poisoners.
