H. diardi has black and white color, shiny surface and white hair all over the body. The head is round, shiny black with a linear white line in the middle. Black eyes on the front of the head. The stomach has an elongated, jointed, black cylindrical shape with black plots at the top of each segment. The legs are long, segmented, shiny black or brownish in color and hairy. Black jumping spiders live arboreal, perch on leaf surfaces, low bushes, trees in forests, agricultural land, roadsides and shade.

Water strider (Ptilomera tigrina)

Water strider ( Ptilomera tigrina ) is an animal species in Gerridae, a predatory insect that spends time on the surface of fast water with back and forth movements with a speed of up to 1.5 m/s to float and is very easily recognized by its habit of always walking and jumping on around water. P. tigrina has an elongated, dark cylindrical body with several bright or silvery white parts. A pair of big eyes at the tip of the head. The stomach has joints and tapers towards the back. A pair of antennae is very long with several joints and stick-shaped legs. The forelegs pair have three sections with two joints and the first is slightly thickened. The second and third pairs of legs are several times the length of the body. Water strider has a very fast movement on the surface of the water to float and target prey near the surface. This species is a model in biophysical research regarding the ability to float on the surface and the ability to move forward quickly. The buoyancy originates f...
