Which has more species Aeonium or Crowea?
Aeonium Aeonium (tree houseleek) is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek "aionos" (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Morocco, and in East Africa (for example in the Semien Mountains of Ethiopia).
Euploea Euploea is a genus of milkweed butterflies. The species are generally dark in coloration, often quite blackish, for which reason they are commonly called crows. As usual for their subfamily, they are poisonous due to feeding on milkweeds and other toxic plants as caterpillars. The latter are aposematically colored to warn off predators from eating them, and the adult butterflies are often mimicked by unrelated species which are not or less poisonous.
