Glermeyjar fastar saman að verpa í vatnið. A large, 36 mm, active, deep red damselfly with black legs and a bronze-black top to the thorax which has broad red or yellow stripes. The female exists in several colour forms varying in the amount of red and black on the abdomen from nearly all black in f. melanotum to mainly red in f. fulvipes. The pterostigma is black. This is one of the earliest species to appear each spring. See more: http://www.british-dragonflies.org.uk...

Pyrrhosoma nymphula is the earliest Odonata species on the wing, appearing in warm Springs in late April. It is found in most habitats except for the most exposed sites. It has a preference for small acidic pools and is able to persist on many very dry sites that have become unsuitable for other Odonata. It is also quick to colonise newly created ponds.

Meyjarflugur (einnig nefndar glermeyjar eða dömlur) (fræðiheiti: Zygoptera) eru annar af undirættbálkum vogvængja, hinn eru drekaflugur (Anisoptera). Meyjarflugur gangast undir ófullkomna myndbreytingu. : http://is.wikipedia.org/wiki/Meyjarfl...

Vogvængjur (fræðiheiti: Odonata) er ættbálkur skordýra sem deilast í tvo undirættbálka, drekaflugur (Anisoptera) og meyjarflugur (Zygoptera), einnig nefndar glermeyjar. Þær eru mjög stór skordýr, sem einkennast af stórum augum og að hafa tvö pör af löngum glærum vængjum með þéttriðnu æðaneti. Í hvíld halda drekaflugur vængjunum láréttum út frá bolnum en glermeyjar leggja þá saman lárétt aftur bolinn. Annar munur á drekaflugum og glermeyjum er sá að á drekaflugum er munur á fram- og afturvængjum en þeir eru nánast eins á glermeyjum. Vogvængjur eru ásamt dægurflugum annar tveggja eftirlifandi ættbálka í Palaeoptera innflokknum. : http://is.wikipedia.org/wiki/Vogv%C3%...

Damselflies undergo incomplete metamorphosis, with an aquatic nymph stage. The female lays the eggs in water, sometimes in underwater vegetation, or high in trees in bromeliads and other water-filled cavities. Nymphs are carnivorous, feeding on daphnia, mosquito larvae, and various other small aquatic organisms, using extendable jaws similar to those of the dragonfly nymph. The gills of damselfly nymphs are large and external, resembling three fins at the end of the abdomen. After moulting several times, the winged adult emerges and eats flies, mosquitoes, and other small insects. Some of the larger tropical species are known to feed on spiders, hovering near the web and plucking the spider from its nest. Damselflies rest their wings together, on both sides of their bodies. Dragonflies, however, have wings that are spread apart, even while resting. : http://en.wikipedia.org/wiki/Damselfly
