Javan lutung (Trachypithecus auratus)

Javan lutung or Javan langur or lutung budeng (Trachypithecus auratus) is a species of animal in the Cercopithecidae, medium-sized monkeys, head and body length 46-75 cm, tail 61-82 cm, weight 7 kg, two subspecies are East Javan langur (Trachypithecus auratus auratus) and West Javan langur (Trachypithecus auratus mauritius).

T. auratus is diurnal. Adult males and females generally have black or reddish body hair, but females have a yellowish white color around the genitals. Children have golden orange body hair.

Food is plants including leaves, fruits and flowers. This species also feeds on insect larvae. The diet consists of 15-27% unripe fruit and 10-15% ripe fruit. They may eat fruits primarily to obtain seeds and prefer leaves which are rich in protein and low in fiber.

Different groups will feed on the same food source without significant aggression. Adult males do not disproportionately feed as often as other group members, females and juveniles.

They live in groups of about 7-20 individuals, including one or two adult males. Females usually have only one cub at a time and help each other raise the cubs. However, female langurs are also very aggressive towards female langurs from other groups.

Lutung budeng inhabits various types of forest including mangrove forest, coastal forest, freshwater swamp forest, lowland rain forest, tropical deciduous forest and mountain forest up to an elevation of 3500 meters. Also found in teak, rasamala, and acacia plantations.

Yellow garden spider (Argiope appensa)

Yellow garden spider ( Argiope appensa ) is a species of spider in Araneidae that lives on the coast to forests on islands in the western Pacific Ocean. Black and yellow females are striking and have a length of 5.1-6.4 cm including long legs, while males are brown and have a length of about 1.9 cm. A. appensa lives on cliffs in the hills at 600 m above sea level in Kewu plain to rice fields in the lowlands. They make nests at a height of 1.5 meters from the ground between teak ( Tectona grandis ), sonokeling ( Dalbergia latifolia ), sonosiso ( Dalbergia sissoo ), crown flower ( Calotropis gigantea ) and various grasses. Yellow garden spiders grow in large sizes, but are not toxic to humans. Advanced builds ball-shaped nets and most of them make stabilizers which are zigzag-shaped lines in nets made of thicker bands. This species spends more time in stationary and sits in the middle of the net with its head down to wait for insects to be entangled in fine silk thread. Unli...

Skyflower (Duranta erecta)

Sinyo nakal or skyflower ( Duranta erecta ) is plant species in Verbenaceae, a broad shrub or small tree, up to 6 m high, stems growing upright or horizontally with broad clumps, many branches, bark light brown, old tree has axillary spines and grows to form dense colonies. D. erecta has bright green leaves, elliptical to ovoid, pointed or rounded ends, sitting opposite, 7.5 cm long, 3.5 cm wide, a main vein in the middle with several small lateral veins, petiole long 1.5 cm. Flowers are light blue or lavender or white, appear in tight clusters as on terminal stems and axils, often curled or pendulous, blooms in summer. The fruit is a berry having a stalk, small round, yellow or orange or white in color, up to 11 mm in diameter, an eye green in front and containing several seeds. Skyflower grows in dry or humid areas and lots of sun, rocky or sandy beaches, forests, farmland and disturbed places. Plants will grow at a rate of up to half a meter per year.

Big-leaved acacia (Acacia mangium)

Big-leaved acacia ( Acacia mangium ) is a species of woody plants in the Acacieae, long oval leaves, growing up to 30 m and straight stems, except in less favorable places will grow only 7-10 m, have hardwood, rough, longitudinal grooved and dark to light brown. A. mangium has shoots with compound leaves consisting of many minor leaves and after growing a few weeks does not produce any more real leaves but the main axis of the petiole of each compound leaves widens and turns into known pohyllocladus or pseudo leaves. Big-leaved acacia has about 142,000 seeds/kg. Long pods form circular threads and are black or brown when ripe. Dry pods will open to expose small black seeds. Trees bind nitrogen to the soil and are a popular species for agroforestry projects. This plant is weather resistant, although it requires special care if it is planted as a garden plant where the leaves are falling a lot. These plants include legumes that grow quickly by increasing height 4 m per year near ...
