Maurits Lieftinck
Maurits Anne Lieftinck informally Maus Lieftinck (18 February 1904 – 13 April 1985) was a Dutch entomologist who specialized in the Odonata, particularly in Southeast Asia, working from the Bogor Museum where he worked for a significant period. Lieftinck was born in Amsterdam, the second son of tobacco-importer Gerrard and Elsabet née Esser. He was educated at the Amsterdam Lycaeum and at the University of Amsterdam (graduating in 1929). He became interested in natural history and joined the Netherlands Entomological Society in 1919 serving as the editor of ''Amoeba'', the periodical of the Netherlands Youth Federation for Nature Study that he founded in 1921. He published on the dragonflies and damselflies of the Netherlands and left his collections to the Amsterdam Museum in 1929. He moved to the Buitenzorg Museum in Dutch Java and served as in-charge of the Laboratory of Marine Research in Batavia. He became a head of the Buitenzorg Museum in 1939 and worked there until 1954. ...

Spreadwing
The Lestidae are a rather small family of cosmopolitan, large-sized, slender damselflies, known commonly as the spreadwings or spread-winged damselflies. Characteristics While most damselflies rest with their wings folded together, most members of the family Lestidae hold them at an angle away from their bodies. The pterostigma (a single dark spot in the meshwork of the leading edge near the tip of each wing) is noticeably elongated. The quadrilateral (a part of the wing venation, close to the body) has an acute angle at the end. The body has a greenish, metallic shine. The superior anal appendages, commonly called claspers (body parts of male insect for clasping the female during copulation) of male spreadwings are long and strongly curved. Breeding takes place in slow-moving or still water in stream backwaters, swamps, marshes and temporary pools. The nymphs have a long abdomen and a distinctive prementum (part of the lower lip). There is one generation per year in North Ame ...

Damselfly
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 the ...
