Harmonia testudinaria, commonly known as the tortoise-shelled ladybird, is a species of ladybird belonging to the family Coccinellidae. The tortoise shelled-ladybird occurs in Australia, New Guinea, Indonesia and (via introduction) Hawaii. [1] [2] [3]
Adult H. testudinaria are beetles about 6 mm long and yellow/light orange with a black net pattern on the elytra. [4] [5] There are also two black stripes running across the pronotum. [1] Adults are entirely yellow when they first emerge, developing their black markings later. [1] [5] There is some intraspecific variation, with adults from New Guinea generally having elytra mostly of one colour except for a black suture and small black spots at the elytral bases. [2]
The larvae are brownish with some creamy markings, while the pupae are orange-yellow. [1] [5]
This species can be found on the leaves and stems of plants. [3] [5]
Tortoise-shelled ladybirds feed on aphids and other insects. [5] One of their prey species is the giant willow aphid, Tuberolachnus salignus. [6]
Harmonia testudinaria begin their life cycle as eggs laid on suitable plants. These hatch into larvae, which moult several times before becoming pupae. After a few days, adults emerge from pupae. [1]
