Crown flower has several secondary metabolites including usharin, alpha and beta-calotropeol, fatty acids, tetracyclic triterpenes, giganteol, kardenolida calotropin, α-amirin, taraxasterol, β-sitosterol, α-amyrin methylbutazone, α-amirin acetate, β-amirin acetate, lupeol acetate, flavonol glycoside.

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

Golden tortoise beetle (Charidotella sexpunctata)

Kepik emas or golden tortoise beetle ( Charidotella sexpunctata ) is a type of leaf beetle species in the Chrysomelidae family, up to 14mm long and bright golden in glass discs. These insects usually live on Ipomoea carnea trees that grow in environments close to water. C. sexpunctata takes refuge in a transparent disc consisting of three parts with four signs as fals legs, a pair of antennas and six legs. This beetle is able to change color if it feels threatened by flowing liquid between the cuticles and the glittering gold color turns into blood red or worn brown. Kepik emas usually lay eggs up to 20 items, white and attached to the branches or on the underside of the leaves. Yellowish or reddish brown larvae will appear from eggs that hatch within 5 to 10 days. Adults and larvae eat leaves which cause large holes.
