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.

God is tools

God and spirit are controversial discussions in science and even mythology will have no place among naturalists and for Darwinians. Apparently this has been final that mythology is a delusional, mystical and superstitious concept that cannot be empirically proven in the world of science.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.


I am a fieldman who goes to the wild every day, along rice fields and forests to watch insects to plants, talk to people especially in villages, visit Hindu-Buddhist temples built in the 8th century, witnessing busyness in mosques, temples and churches.

I feel something is missing in the view of naturalists and Darwinians. There are short moments that are missed in analyzes in the timeline of human evolution. These little moment…

Earleaf acacia (Acacia auriculiformis)

Akasia or Papuan wattle or cormis or earpod wattle or earleaf acacia (Acacia auriculiformis) are acacia species in Fabaceae, endemic in Papua and Papua New Guinea, growing at an altitude of 0 to 400 meters above sea level at warm temperatures and able to live in rainfall is very low at 200 mm/year on soils pH 4-9.

A. auriculiformis grows well on damaged land and is able to fix nitrogen. Very tolerant of environmental stress, barren and marginal land, clay, high salinity or waterlogged. Evergreen tree despite the dry season where other plants have shed leaves. Growth of up to 30 meters and diameter of 80 cm.


Akasia has a phylum where leaves are incomplete without leaf strands, but leaf stems will widen. Trees have phylaxis with scattered types where the phylogens bend like auricles which form the basis for identification of this species. Venation in the phyla is dominant in the longitudinal direction, 10-20 cm long and 2-6 cm wide.

Flowers are in the form of grains, short-stemmed and a …
