	This is a day biting mosquito.  Hawaii was mosquito free before 1826, when the night biting mosquito arrived. The day-biting mosquitoes reached the islands around 1892-1897.

A common mosquito in Hawaii and is bigger than the Tiger Mosquito. It's a night biter and the most effective vector of West Nile virus. [Species identification made by Nieu Nguyen and Cyntiha Harrison of the New Orleans Mosquito Control program.]

	Body length = 3mm.
	Mosquito body length about 4 mm.

This fly is 5 mm long.  It hovers with others in small groups.

This fly has a body length of 12mm. ID by Frank Howarth of the Bishop Museum.

	Side.
	Ventral.  Body length = 3 mm. Identification made by Dr. Norman Woodley, National Museum of Natural History.

This fly is about 2 mm long.

This fly is about 5 mm long.

(Immediate left) Dorsal view.  Fly length = 3 mm.

	Dorsal view.
	Ventral view.  Note protrusion from lower jaw!  Body length about 1 cm.

Body length = 4 mm. Identification made by Dr. Martin Hauser, California Department of Food and Agriculture.

	Side view. Body length = 3 mm.
	Dorsal view. This is an introduced species.

This fly is about 1.5 cm long. Identification made by Dr. Martin Hauser, California Department of Food and Agriculture. The soldier fly was first seen in 1930 in the fields of the Hilo Sugar Co.; now it is found on all of the major Hawaiian islands.

	Body length is 6 mm. Two black spots on clear wings and yellow patch on dorsal side of abdomen. This fly is a member of the Stratiomyidae family. Species identification by Norm Woodley at the USDA Systematic Entomology Laboratory.

Body length = 5mm; leg length = 15mm. Per David Preston at the Bishop Museum  “It is a very common lowland crane fly species. It is an immigrant recorded from the Marquesas, Fiji, Tahiti and Samoa. The species can be recognized by the strongly arched vein R3, and broad black apices of the femora. It breeds in tree holes, leaf axils, and decaying vegetation.”

Body length = 4mm.  There are no spots on the wings.

Body length = 1cm,  leg length = 4 cm.  This is a Tipulidae, possibly Tipula oropezoides. Despite the common name “mosquito eater” adult crane flies feed on nectar or they do not feed at all; most crane fly species live only to mate and die once they become adults.

Body length = 1 cm, leg length = 2.5 cm.

Fly body length = 4mm. Bishop Museum says: the fly is Euxesta annonae (Fabricius, 1794), a picture-winged ottitid fly.

White Gnat

Body length = 2 mm.

Body length about 1 mm. Identification made by Dr. Martin Hauser, California Department of Food and Agriculture.

Body length 2 mm.  These midges fly in small swarms.  This is probably the endemic species Chironomus hawaiiensis.

	Dorsal view.
	Side view.
	Ventral view. Body length about 7 mm.  This may also called “Nesomicromus vagus” in the book by Howarth and Mull (Hawaiian Insects and their Kin) and is endemic on all major Hawaiian islands.

	Side view.  Body length, 6 mm.
	Closer view of large eye.

	Ventral view with fuzzy debris on back.
	Close-up ventral view with fuzzy debris removed from back.
	Dorsal view with fuzzy debris on back.
	Close-up dorsal view with fuzzy debris removed from back. This bug collects various debris on its’ back which I presume is a method of disguise.  It looks like a small pile of fuzz and is only noticeable when it moves.

	Fly on leaf.  Fly body about 0.5 mm long.
	Whitefly pupa with long glassy setae on the dorsal surface.

	Front view.  Height = 3mm.
	Side view.  Length = 1.5 mm.

	Body length about 3 mm.  Per Frank Howarth of the Bishop Museum: “It’s a moth fly, family Psychodidae; the species is Clogmia albipunctata (Williston, 1893). The larvae of this species are scavengers in highly polluted damp to aquatic habitats and are sometimes common in Hawaiian homes where they live in sink drains. The species has been introduced worldwide by humans. They are harmless to humans.”  Note: this specimen caught outside near a fish pot with water plant.

	This fly is 3 mm long.  It is probably a type of picture wing fly (Euxesta sp.)

This fly is 2 mm long.

Body is 3 mm long.

This fly is 2 mm long.

Body length is 12 mm.

	Dorsal view.
	Side view. Body length is 7 mm. Per David Preston of the Bishop Muesum “This is the oriental fruit fly Bactrocera dorsalis (Hendel) which attacks over 300 cultivated and wild fruits including Annona (cherimoya, atemoya, sugar apple), avocado, banana, bittermelon, citrus, coffee, guava, macadamia, mango, papaya, passion fruit, peppers, persimmon, and tomato. Accidentally introduced into Hawaii in 1944 or 1945 (Fullaway, 1947).”

	Body length is about 1 cm.
	Per Frank Howarth of the Bishop Museum: “the animal is a true fly, order Diptera, not a wasp, but the species has evolved to fool potential predators. The species is Taeniaptera angulata (Loew, 1866), family Micropezidae, “the stilt-legged flies.” It’s a relatively recent introduction to Hawaii. The larvae live in damp rotting fleshy plant material, such as rotting sugar cane.”
