Yes, Dragonflies do have a pair of antennae. They are very tiny and difficult to see. If you look at the photo on the right you will just be able to see the antennae between the front of the eye and the front of the face of this Emperor dragonfly. As dragonflies rely much more on their eyesight than on a sense of touch or smell, they do not need the large antennae found on some beetles and moths.

Possibly the earliest reference to the name is from Francis Bacon's "Sylva Sylvarum: or a Naturall Historie in Ten Centuries." (a curious hotch-potch of experiments, observations, speculations, ancient teachings, and analytical discussions on topics ranging from the causes of hiccups to explanations for the shortage of rain in Egypt).

Mainly, adult dragonflies eat other flying insects, particularly midges and mosquitoes. They also will take butterflies, moths and smaller dragonflies. There is one Asian species which takes spiders from their webs! The larvae, which live in water, eat almost anything living that is smaller than themselves. The larger dragonfly larvae are known to catch and eat small fish or fry. Usually they eat bloodworms or other aquatic insect larvae.

Dragonflies do have enemies. Among the species that catch and eat adult dragonflies and damselflies are birds (e.g. Wagtails and Hobbies), Spiders (many damselflies are caught in webs), Frogs, and larger species of dragonflies (which catch and eat other dragonflies and damselflies). In the larval stage, which is spent underwater, they are preyed on by fish, frogs, toads and newts, other water invertebrates - and Kingfishers (see photo below).

Dragonflies and damselflies belong to the insect order known as Odonata, meaning "toothed jaw" - their mouthparts are serrated. They are often referred to collectively as "dragonflies", however there are two different sub-orders. Damselflies are insect in the sub-order Zygoptera (meaning "yoke-winged"). All four wings are near enough equal in size and shape. They are usually small, weakly flying insects that stay close to the water margins or water surface.

No, although large dragonflies if held in the hand will sometimes try to bite, but fail to break the skin. They have a lot of "folk names" which imply that they do (such as Horse stinger), but they don't use their egg-laying tube (ovipositor) for stinging. They also don't bite (people) but they are a fearsome predator of other flying insects.

There are many legends and myths about dragonflies and damselflies from all parts of the world. Many are evident from their common nicknames. In the UK, Dragonflies were called 'Horse-Stingers'. This name may come from the way a captured dragonfly curls its abdomen as if in an attempt to sting. Another possible explanation of this name is that the big Aeshnids etc. are/were often seen flying round horses in fields. Here they were actually feeding on the flies attracted to the horses.

It would be odd if it were true. The Touareg actually has several antennas, including AM radio, FM radio, long-range remote control, four short-range remote control, four tire pressure monitor, and in some vehicles, GPS, and OnStar antennas. Some of these antennas, including the GPS and radio antennas are in the rear glass on either side of the vehicle.

When dragonflies and damselflies first emerge from their water-borne larval stage, most have very muted colours. Depending on weather conditions, it can take a few days for them to gain their bright adult colour. Common Blue damselflies are often a pale pinkish-brown rather than sky-blue on first emergence. Some damselflies, Blue-tailed are a good example, undergo a gradual colour change as they age.

Several species of dragonfly are known to collect in large aggregations or swarms. In Europe, the Migrant Hawker (Aeshna mixta) and the Four-spotted Chaser (Libellula quadrimaculata) have been observed to do this. In most cases this appears to be due to very favourable feeding conditions in the locality. It may also be a "courting" group with males actively searching for females. This is less likely as males are much more aggressive to each other when looking for a mate.

The Feelers are a 3 piece band, originally from Christchurch, New Zealand. They are James Reid (vocals), Matt Thomas (bass) and Hamish Gee (percussion). Opshop guitarist, Tim Skedden, also plays guitar with the band at concerts.

They travel around a lot - as soon as any tour dates are confirmed, they'll be posted on the tour page. Rumoured tours and concerts will be on the forum - the tour page is for confirmed concerts only. Please email me if you know of any (possible) upcoming concerts which aren't mentioned on the site.

No. The official Feelers site is currently http://www.thefeelers.co.nz. I am not associated with The Feelers in any way - I am not part of the band, their crew, or their management. I am just a fan, like you. Any emails sent to me intended for The Feelers will be forwarded on to them, and whenever possible, I will try to answer any questions you may have.

For recreational and traveling purposes, standard GPS receiver antennas can be classified into two groups: External antennas linked via cable to the GPS receiver, are normally much more sensitive than internal antennas and allows for comfortable positioning within a vehicle, boat or other enclosures. Some ",active", external antennas are available to actively amplify the antennas signal before sending it to the GPS receiver in order to compensate for the signal loss through the cable.

the shortest, a dragonfly's life-cycle from egg to death of adult is about 6 months. Some of the larger dragonflies take 6 or 7 years! Most of this time is spent in the larval form, beneath the water surface, catching other invertebrates. The small damselflies live for a couple of weeks as free-flying adults. The larger dragonflies can live for 4 months in their flying stage. In Britain, lucky Damsels seldom go more than two weeks and Dragons more than two months.

Dragonflies certainly do eat large numbers of flying pest species, but using them to control these pests is not really feasible. There have been a number of studies carried out and only in very restricted and tightly controlled environments have Dragonflies, or their larvae, been shown to be able to control pest numbers. In the open, there is no reason to suppose that Dragonflies introduced to a pest rich habitat will stay there.

The design of items like antennas and power-supplies is very mission-oriented, and should be tailored to each individual CubeSat. The CubeSat Kit is a general-purpose kit, and is designed to satisfy the basic requirements of the CubeSat specifications. With the CubeSat Kit, you don’t have to worry about building a sturdy yet light enclosure, adding Remove-Before-Flight and Launch Switches, creating a working connector scheme, picking a microcontroller, etc.

The best antennae mount is the Lucas Tri-Polar Magnetic mount antennae. The poles have been shifted 90 degrees so it sticks to aluminum. Rovers North sells them. Ask for Lanny and tell him you need a Lucas Tri-Polar Magnetic mount CB antennae. I think they're on special in this month's flyer. [BM]

Dragonflies are one of the predators of mosquitoes and have been deployed as biological control agents in rural areas in countries such as Cambodia and Vietnam. However, their extent of control is limited in Singapore due to the lack of larvae habitat (i.e. pond) and difference in adult behaviour and habitat. EHI has tested several commercial adult mosquito traps of various designs (baited with a range of attractants, including carbon dioxide) for surveillance and research purposes.

quot;The dragonfly, is any one of numerous stout-bodied insects of the order Odonata, sub-order Anisoptera, that prey on mosquitos and other insects and are distinguished from the damselflies by the horizontal position of the wings when at rest" According to Random House Unabridged. The Symbolism of the dragonfly is another thing. Here are some thoughts gleaned from various internet sources.
