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.
Hystrichopsylla schefferi
Hystrichopsylla schefferi, also known as the mountain beaver flea and giant mountain beaver flea, is a parasitic holarctic insect belonging to the order Siphonaptera, the "siphon-wingless" (fleas). The fully grown adult can measure as much as in length, and it is the largest living flea in the world. It is native to the American Northwest. Though most members of the genus "Hystrichopsylla" are not strongly associated with any particular host animal and will generally parasitize insectivores and rodents, "H. schefferi" is monoxenously associated with the mountain beaver with which its range is coterminous. The fleas of the family Hystrichopsyllidae, along with the family Pulicidae, are the oldest of fleas in evolutionary history. "H. schefferi" can be distinguished from the very similar and closely related species "Hystrichopsylla gigas dippiei" by the number of spines in the pronotal comb, as "H. g. dippiei" has 36 and "H. schefferi" has 46.
