	How to identify a whirligig beetle
		Whirligig beetles are from the Gyrinidae family of insects in the Coleoptera order which also means beetles.
		This is often done on the stems of plants or in muddy areas with the beetles remaining for around a week prior to emerging as new adults to form large aggregations on the waters surface.
		This alerts the whirligig beetle when other insects are struggling on the waters surface or if an object is in their path that will need to be avoided.

	Beetles
		Beetles can be found in almost all habitats, but are not known to occur in the sea or in the polar regions.
		Beetles are generally characterised by a particularly hard exoskeleton, and the hard wing-cases (elytra) which tend to cover the hind part of the body and protect the second wings, the alae.
		In these beetles the testes are tubular and the first abdominal sternum (a plate of the exoskeleton) is divided by the hind coxae (the basal joints of the beetle's legs).

		Beetles are extremely diverse and are one of the most successful groups of animals in the world.
		Their front wings (called elytra) are hard sheaths that protect the beetles' hind wings and cover the breathing pores.
		Beetles also have diverse mouthparts, and they eat anything from hardwood to the ooze from rotting fungi.

	Beetle fights bass in mouthwash duel: Science News Online, Oct. 7, 2000
		A whirligig beetle seeps white goo when pestered, and that slow ooze—instead of a big squirt—gives the beetle a chance in a life-or-death contest inside a fish's mouth, say Cornell University researchers.
		Likewise, they suggest that the beetle's slow doling out of repellant could be a common defense in small water creatures.
		They inserted whirligigs randomly in a series of mealworms, and the bass ate all 197 mealworms but only 3 of 96 beetles offered.

	Wildlife of Sydney - Fact File - Whirligig Beetle
		The whirligig beetles, including Macrogyrus striolatus, are named after their habit of swimming in circles on water surfaces.
		Whirligig beetles are among the most specialised beetles for living in and on water because all their legs are modified into flat paddles and their eyes are split to give both underwater and above-water vision.
		Whirligigs feed by capturing and eating dead or injured insects on the water surface with their elongated front legs.

	water beetle — FactMonster.com
		The predaceous diving beetles (family Dytiscidae) are a large group, widespread in quiet streams and ponds.
		There is a cavity beneath the wings for holding an air supply, so the diving beetle can remain submerged for long periods; however, the insect often hangs head down from the surface, exposing the openings (spiracles) of the last two of its breathing tubes, located at the tip of the abdomen.
		The water scavenger beetles (family Hydrophilidae), of similar appearance, are abundant in marshy places in warm parts of the world and feed on water plants and decaying matter.

	Can you tell me something about the whirligig beetle? - Blurtit
		The whirligig beetles belong to the family Gyrinidae and their aquatic ancestors floated about on water as far back as 180 million years ago.
		Whirligig beetles are small and shiny and are either fl or dark bronze in colour.
		The beetles move through the surface film of the water by moving only their middle and rear pairs of legs.

	Whirligigs (Beetles) (Site not responding. Last check: 2007-11-06)
		Because of their speed and the randomness of their swimming, it wasn't possible to observe the beetles' actual means of locomotion in their natural habitat, so we went back to the lab to fetch a long-handled dip net to collect a few of the Whirligigs for closer examination.
		For one, the tip of the Whirligig's abdomen was edged with a white fringe that probably serves as a point of attachment for the diving bubble we observed through the glass.
		Although we associate Whirligig Beetles with aquatic habitats, they are also masters of the air, using their membranous wings to fly from place to place.

		Beetles are the largest group in the Animal Kingdom, representing a fourth of all animals.
		For example, long and slender legs are made for speed (ground beetles, Carabidae family); broad and ridged legs are for digging (dung beetles, Scarabaeidae family); legs curved and shaped like a paddle are for swimming (water beetles, Hydrophilidae family); and large hind legs are for hopping (flea beetles, Chrysomelidae family).
		Whirligig beetles (Gyrinidae family), which swim on the surface of ponds, have divided eyes: one half for vision under water, the other for seeing above the water.

		Diving beetles and whirligigs are common adult beetles which stick around the pond.
		Most beetle larvae can be identified separately from other insects because their body is often covered in a much thicker, fl plating and some species have long filaments off the sides of their bodies.
		A few other species with aquatic larvae are the water scavenger beetles (160 species, 0.3 to 1.5 inches long), dryopids (25 species, 0.5 inches), elmids (75 species, 0.3 inches), leaf beetles (0.1 inches), and tiger beetles (0.5 inches).

		Beetles are commonly seen swimming or crawling among water plants or on the bottom of shallow pools, feeding mostly on dead or decaying vegetation.
		These fast-moving beetles are often seen swimming in groups in endless gyrations or circular "skating" movements, in a spot on the water surface.
		Unlike other water beetles which move their legs alternately when swimming, these beetles stroke them together like oars as the backswimmer bugs do.

	Beetles
		Beetles have "sheathed" wings: their forewings have become protective shells, called "elytra," for their membranous hind wings, which actually do the flying.
		This is only one of fourteen identifying characteristics of beetles, but one of the two earliest characteristics to appear: beetles have had elytra for the past 285 million years.
		Notable in its absence is the Convergent Ladybug Beetle (Hippodamia convergens).
