One thing about visiting the tropics, it helps not to be freaked out by large insects! This huge Tarantula Hawk Wasp was on the window sill in the restaurant of the Sapo Dorado. Our guide, Willy, is an ecologist and he shared many interesting facts about the plants and animals with us. He told us that male wasp's size depends on how big the tarantula the was that his grandmother laid his father's egg on! The larger the food source for the larva, the larger the adult will be. The male wasps gather in a lek to attract a female, she will choose the largest one as her mate (thus carrying on the healtiest genes).
