Scarlet skimmer (Crocothemis servilia)

Capung Merah or scarlet skimmer or ruddy marsh skimmer (Crocothemis servilia) is a dragonfly species in Libellulidae and has two known subspecies, Crocothemis servilia servilia (Drury, 1773) which has a mid-dorsal black line and Crocothemis servilia mariannae (Kiauta, 1983) which does not have a mid-dorsal black line.

C. servilia is a blood-red dragonfly, medium size and thin black lines along the middle abdomen, blood red eyes and purple side, ferruginous bright thorax and often blood red on the dorsum.

Dlium Scarlet skimmer (Crocothemis servilia)

Scarlet skimmer has a blood red belly with a long and narrow black mid-dorsal carina. Females are similar to males, but thorax and abdomen are brown-olive and mid-dorsal black carina is rather wide. These insects are found on the shore to a height of more than 3,000 m above sea level.

Dragonflies breed in aqueous environments including lakes, ponds, rivers, swamps and rice fields as a place to lay eggs and spend their pre-adult childhood. Capung are strong pilots and have a wide range of areas. They spread widely in the forests, gardens to the yard and the urban environment.

The life cycle from egg to death after adulthood varies between six months to a maximum of six or seven years. Dragonflies lay eggs in plants in the water. Some species love in stagnant water, but others like to put eggs in silent water.



The larvae live and develop in the bottom of the waters, doing metamorphosis into nymphs and finally out of the water as adult dragonflies. Most cycles are spent as nymphs beneath the surface of the water using internal gills to breathe.

Larvae and nymphs are malignant carnivores. Large nymphs even hunt and prey on tadpoles and fish. Adult dragonflies only live for four months.

Javan broadhead planarian (Bipalium javanum)

Cacing palu or Javan broadhead planarian ( Bipalium javanum ) is a species of animal in Geoplanidae, hermaphrodite, living on the ground, predators, often called only hammerhead or broadhead or shovel worms because of wide heads and simple copulatory organs. B. javanum has a slim stature, up to 20 cm long, up to 0.5 cm wide, head wide up to 1 cm or less, small neck, widening in the middle and the back end is rounded, all black and shiny. Javan broadhead planarians walk above ground level by raising their heads and actively looking left, right and looking up using strong neck muscles. Move swiftly, track meander, climb to get through all obstacles or make a new path if the obstacle is too high. Cacing palu track and prey on earthworms and mollusks. They use muscles and sticky secretions to attach themselves to prey to lock in. The head and ends of the body are wrapped around and continue to close the body to stop prey reactions. They produce tetrodotoxins which are very strong...

Swietenia mahagoni and Swietenia macrophylla, the differences

SPECIES HEAD TO HEAD - To date, mahogany ( Swietenia Jacq.) is recorded as having four species: West Indian mahogany or small-leaved mahogany ( Swietenia mahagoni (L.) Jacq.), big-leaf mahogany ( Swietenia macrophylla King), Honduran mahogany ( Swietenia humilis Zucc.) and Swietenia × aubrevilleana StehlĂ© & Cusin. The debate over the number of taxa in the genus is still not resolved. Some researchers believe that there are only two species: S. mahagoni and S. macrophylla . I agree with that opinion and the two species can only be differentiated by the size of the leaves. All species in this genus have similar morphology except for leaf size. The following is the key to identifying these two species. S. mahagoni has a stalk length of around 37 cm with 5-6 pairs of strands. The strands are about 10 cm long and about 3.5 cm wide. S. macrophylla has a stalk length of up to 45 cm with 4-5 pairs of strands. The strands are up to 31 cm long and up to 8 cm wide. By Aryo Bando...

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...
