  Toxorhynchites - Wikipedia, the free encyclopedia
Toxorhynchites, also known as mosquito hawks, is a large cosmopolitan genus (nearly 100 species), and one of the few types of mosquito that does not suck blood.
The larvae of one jungle variety, Toxorhynchites splendens, consume larvae of other mosquito species occurring in tree crevices, particularly Aedes aegypti.
In a scientific paper on Toxorhynchites, USM associate professor Dr Yap Han Heng wrote: “We believe we have a vegetarian which does no harm to any human being, and is at the same time a deadly foe to the young of other kinds of the genus (mosquitoes).”

 Bromeliad Biota - Mosquitoes - Biological Control
Toxorhynchites larvae may conserve their prey in the manner of stock-rearers (28), and may be unsuitable as biocontrol agents where survival of the prey is limited by food availability.
Collection records suggest that Toxorhynchites guadeloupensis from the West Indies and Toxorhynchites superbus from Mexico south to Colombia are primarily inhabitants of bromeliads (10).
Toxorhynchites haemorrhoidalis (which, despite the different name, is very possibly the same species as the Toxorhynchites superbus mentioned above) larvae inhabit flower bracts of Heliconia, leaf axils of aroids, and tanks of the bromeliads Aechmea nudicaulis and Aechmea aquilega in coastal Venezuela (23).

 God of Insects - Museum: Toxorhynchites rutilus
Toxorhynchites rutilus belongs to a genus of unique mosquitoes.
Toxorhynchites species are uncommon due to the hostile nature of their larvae.
Despite this, they have been used in the successful control of "container-breeding" mosquitoes in Japan, Southeast Asia, the Caribbean and the U.S.A. The specimens pictured were collected in Westchester Co., NY and are probably the subspecies T. r.

A mark-release-recapture study of T. brevipalpis in a tyre dump in Dar es Salaam, Tanzania estimated the population to be 1292 females and 2268 males per hectare (Trpis, 1973).
A method devised for 32P labelling Toxorhynchites rutilus rutilus (Coquillett) in the field had the potential of being used to track the dispersal of released adults, in addition to the dispersal of eggs from released females (since 32P is also passed on to the eggs) (Smittle & Focks, 1986).

 The carnivores, Toxorhynchites
Predatory mosquitoes in the genus Toxorhynchites are the most common arthropods which have been used for control of "container-breeding" mosquitoes.
At least one, Toxorhynchites rutilus, has a subspecies (septentrionalis) that is found as far north as 40 degrees N latitude in Connecticut and southern New York.
Toxorhynchites are unusually large mosquitoes; the wingspan may exceed 12 mm; the body length may exceed 7 mm.

Toxorhynchites were first recognised as a distinct group in 1827 when Robineau-Desvoidy proposed that they be known as Megarhinus (Robineau-Desvoidy, 1827).
There have, however, been many regional studies of the taxonomy of Toxorhynchites mosquitoes (Table 4), although the taxonomy of the Toxorhynchites species of the New World is still thought to need clarification (Steffan, 1975).
Descriptions of new Toxorhynchites species or species new to a particular area have been added to the literature as they have been identified.

Traditionally placed in its own subfamily and regarded as sister group to Culicinae, recent morphological data instead have suggested that this distinctive genus belongs well within the Culicinae.
Published molecular systematic studies seemingly conflict with this new morphological data or are ambiguous.
The mitochondrial gene data that we present show good potential for elucidating suprageneric relationships in Culicidae, and strongly support the placement of Toxorhynchites well within the Culicinae.
