Lestes Sponsa
''Lestes sponsa'', is a damselfly, with a wide Palaearctic distribution. It is known commonly as the emerald damselfly or common spreadwing. Both males and females have a metallic green colour and when resting its wings are usually half opened. Behaviour One of the larger damselflies, this species is most common in July and August. It is often found by ponds and lakes, and is very rarely seen along flowing water. Emerald Damselflies like to perch among reeds, their colour providing good camouflage. They are not as strong fliers when compared to other common damselflies such as the common blue or large red damselflies, but they are more likely to be seen on misty, rainy days then those species. When disturbed they usually do not fly very far away, landing on another perch a few yards away. Their habit of perching with their wings half open is characteristic of the family Lestidae and gives rise to their other common name of spreadwings. A population can consist of several hundre ...

Hampshire
Hampshire (, ; abbreviated to Hants) is a ceremonial county, ceremonial and non-metropolitan county, non-metropolitan counties of England, county in western South East England on the coast of the English Channel. Home to two major English cities on its south coast, Southampton and Portsmouth, Hampshire is the 9th-most populous county in England. The county town of Hampshire is Winchester, located in the north of the county. The county is bordered by Dorset to the south-west, Wiltshire to the north-west, Berkshire to the north, Surrey to the north-east, and West Sussex to the south east. The county is geographically diverse, with upland rising to and mostly south-flowing rivers. There are areas of downland and marsh, and two national parks: the New Forest National Park, New Forest and part of the South Downs National Park, South Downs, which together cover 45 per cent of Hampshire. Settled about 14,000 years ago, Hampshire's recorded history dates to Roman Britain, when its chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Univoltine
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odonata Of Asia
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The wor ...

Damselflies Of Europe
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but their ...

Lestes Parvidens
''Chalcolestes parvidens'', formerly ''Lestes parvidens'', is a damselfly of the family Lestidae. It has a metallic green body and at rest it holds its wings away from its body. Its common name in English is the eastern willow spreadwing. Taxonomy The genus ''Chalcolestes'' is separated from ''Lestes'' because of differences in their larvae. ''C. parvidens'' is closely related to '' C. viridis'' and used to be considered a subspecies of ''C. viridis'', however there are small morphological differences between the two species both as adults and larvae and analysis of proteins from the two species, by electrophoresis, also supports their separation into two species, but they are hard to tell apart in the field. Distribution and habitat ''Chalcolestes parvidens'' is found in eastern and central Europe, in Croatia, Bulgaria, Greece, Italy, Syria, Jordan, Israel and Turkey. It is found on islands in the eastern Mediterranean; on Cyprus, Corsica, Crete and Sicily. In Italy and the Bal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lestes Viridis
''Chalcolestes viridis'', formerly ''Lestes viridis'', is a damselfly of the family Lestidae. It has a metallic green body and at rest it holds its wings away from its body. Its common name is the willow emerald damselfly, the green emerald damselfly, or the western willow spreadwing. It has an elongated abdomen and pale brown spots on its wings and resides in areas of still water with overhanging trees. Taxonomy The genus ''Chalcolestes'' is separated from ''Lestes'' because of differences in their larvae. A closely related species '' C. parvidens'' used to be considered a sub-species of ''C. viridis''. ''C. parvidens'' occurs in Greece, Bulgaria, Croatia and in Italy; near Rome it flies with ''C. viridis'' in the same ponds. There are small morphological differences between the two species both as adults and larvae and analysis of proteins from the two species, by electrophoresis, also supports their separation into two species, but they are hard to tell apart in the field.

Lestes Sponsa 2(loz)
''Lestes'' is a genus of damselfly in the family Lestidae. The family hold their wings at about 45 degrees to the body when resting. This distinguishes them from most other species of damselflies which hold the wings along, and parallel to, the body when at rest. The name ''Lestes'' comes from the Greek word λῃστής (lēistēs) meaning ''predator''.
