Green weaver ant (Oecophylla smaragdina)

Rangrang or Asian weaver ant or green weaver ant (Oecophylla smaragdina) is a species of insects in Formicidae, arboreal, rather large ants that are known to have high ability in forming webbing for nests, brown-red-green, social insects and forming colonies in very high populations.

O. smaragdina creates territorial, fierce temperament and attacks anything that approaches the area. Many tree owners in Southeast Asia use them to preserve fruit. The larvae are known as Kroto which are favored by birds being a secondary trading commodity for additional income by farmers.

Ant Weaver has two species that are still alive is the Asian weaver ant (O. smaragdina) which is widespread in tropical Asia and Australia, African weaver ant (O. longinoda) inhabits the tropics in Africa, while the other species in this genus are fossils.

They are the dominant ants in the open forest and make leaf nests which are held together with larval silk. Ants have been important in research on the integration of control, communication, territoriality, colonizing life and controlling agricultural pests.

Weaver ant is a true social insect, has a social structure and the life of the colony is very dependent on the tree. The queen are females, measuring 20-25 mm, green or brown in color and has the duty to spawn babies. The male is in charge of marrying the queen and dying.

The worker are females, measuring 56 mm, orange and greenish, in charge of caring for young ants. Warriors are females, measuring 810 mm, generally orange in color, having strong long legs, long antennae, large jaws, guarding nests, searching and gathering food for all colonies and building nests.

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

New living fossil, Amethyst worm lizard (Amphisbaena amethysta), from Espinhaço Mountain Range, Brazil

NEWS - New species from the northern Espinhaço Mountains, Caetité municipality, Bahia state, Brazil. Amethyst worm lizard ( Amphisbaena amethysta ) is the 71st species of the genus with 4 precloacal pores and the 22nd species of Caatinga morphoclimatic domain. Identification of the new species shows the reptiles of the Mountains are far from complete and may contain greater diversity of endemic taxa. A. amethysta can be distinguished by its anteriorly convex snout, slightly compressed and unkeeled, pectoral scales arranged in regular annuli, four precloacal pores, distinct head shield, 185-199 dorsal and half annuli, 13-16 caudal annuli, a conspicuous autotomy spot between the 4th-6th caudal annuli, 16-21 dorsal and ventral segments in the middle of the body, 3/3 supralabials, 3/3 infralabials and a smooth and rounded tail tip. A. amethysta occurs in areas with an average elevation of 1000 meters in patches of deciduous and semi-deciduous forests associated with valleys, slopes, fore...
