Toxorhynchites
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
Nomada
With over 850 species, the genus Nomada is one of the largest genera in the family Apidae, and the largest genus of cleptoparasitic "cuckoo bees". They occur worldwide, and use many different types of bees as hosts, primarily the genus "Andrena". As parasites, they lack a pollen-carrying scopa, and are often extraordinarily wasp-like in appearance, with red, black, and yellow colors prevailing, and with smoky (infuscated) wings or wing tips.
