The Centaur Oakblue

Arhopala centaurus

Description

The male Arhopala centaurus has a purplish blue upper wing with a dark, thread-like outline on the front, while the female is paler with a broader black outline. The underside of the wing is brown with a dark brown hue and a pale brown border in both sexes. This species has a pointed forewing crest, a white-tipped tail at the tip of 2 veins on the hind wings. In addition to distinguishing this species from the others is the presence of a silvery green line that divides the spots on the forewing cells.

Larva: Arhopala centaurus larvae are yellowish green in color with a reddish band on the dorsal, flat shape with long setae on the lateral and dorso-lateral. At the next instar, the dorsal reddish band gets wider and the color becomes brownish red.

Pupa: Arhopala centaurus pupae are lycaenid, brown, 19-20 mm long.

Diet and Nutrition

Arhopala centaurus larvae eat leaves from a number of host plants from different families, one of which is Macrosolen cochinchinensis. These caterpillars also have a symbiotic relationship with weaver ants or kerengga (Oecophylla smaragdina).

Diet : Herbivore (larva), Nectarivore

Mating Habits

Zemeros flegyas reproduce by laying eggs (oviparous), the eggs are laid individually under the leaves of the host plant. Eggs are white in color and smooth.

Life cycle (Metamorfosis) : It takes 2.5-3 days for the eggs to hatch. The newly hatched has a yellowish green color, as it grows, the color of the body becomes more yellowish and reddish dorsal bands appear on the last few segments of the abdomen. After 1.5-2 days of growing on the first instar, and reaching about 3mm in length, the caterpillar moves to the next instar. Even at this early stage, the dorsal nectary organs and tentacle organs are seen in the 7th and 8th abdominal segments, respectively. The 2nd instar caterpillar reaches a length of about 5.5 mm, and after about 2 days at this stage, it will molt again. The 3rd instar caterpillar is prominently marked with a rather wide dorsal band, the 3rd instar takes about 2-2.5 days to complete with a body length of about 9.5 mm. The 4th instar delivers a further “boost” to the back band. Now the ribbon is made more prominent with a narrow white area appearing inside the dark line. Towards the tip of this instar, the spiracles coiled an orange-brown ring. The 4th instar takes about 2.5-3 days to complete with a body length of up to 20mm. The 5th instar caterpillar has a similar but more conspicuous mark. After 5-6 days of feeding and reaching a length of about 31-32mm, the caterpillar slowed down and completely stopped food intake for about 1 day. During this time, his body length got shorter and shorter. Soon became an immobile prepupa in the shelter. Nine to ten days later, the cocoon turns slightly darker, first on the wing pads and chest, then gradually on the belly. The extent of the blue patches on the wing pads provides an early indication of the imminent adult sex. The next day, the pupal stage ends with the appearance of the adult butterfly.
