Spotted tortoise beetle (Aspidimorpha miliaris)

Spotted tortoise beetle (Aspidimorpha miliaris) is a cosmopolitan insect in some families of Ipomoeaceae, Convolvuceae and Cucubitaceae plants. This species has perfect metamorphosis (holometabola) consisting of stages of eggs, larvae, pupae and imago.

The spotted tortoise beetle is about 15 millimeters long. Larva has gregarious habits. Imago uses wings to fly from leaf to leaf, but they prefer to walk quickly to navigate the surface and stalks to save energy.

A. miliaris performs a full cycle of 83-94 days in which the egg period to emergency pupa is 75-82 days and the pre-productive period is 8-12 days. Eggs are placed in groups in the ootheca and each group consists of 20 yellow-orange eggs. Females are able to produce 15 oothecas during life.

Eggs are oval, reddish yellow in ootheca grayish brown and last for 6-14 days. The pupa is yellowish, the back has black fur, lasting 10-14 days. Imago is shaped like a turtle with more yellow elitra.

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...
