Sybra alternans is a species of beetle in the family Cerambycidae. It was described by Wiedemann in 1823. [1] It is known from Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Taiwan, Indonesia, Mariana Islands, Caroline Islands, Marshall Islands, and the Philippines. It was introduced in Hawaii in 1917, as well as Florida. Its diet includes plants such as Ananas comosus , Canavalia ensiformis , Musa × paradisiaca , Ocimum basilicum , Phaseolus vulgaris , Pittosporum tobira , Vachellia farnesiana , and Xanthium strumarium .
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 80,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Myanmar, officially the Republic of the Union of Myanmar and also known as Burma, is a country in Southeast Asia. Myanmar is bordered by India and Bangladesh to its west, Thailand and Laos to its east and China to its north and northeast. Myanmar is the largest of the mainland Southeast Asian states. To its south, about one third of Myanmar's total perimeter of 5,876 km (3,651 mi) forms an uninterrupted coastline of 1,930 km (1,200 mi) along the Bay of Bengal and the Andaman Sea. The country's 2014 census counted the population to be 51 million people. As of 2017, the population is about 54 million. Myanmar is 676,578 square kilometres in size. Its capital city is Naypyidaw, and its largest city and former capital is Yangon (Rangoon). Myanmar has been a member of the Association of Southeast Asian Nations (ASEAN) since 1997.
Thailand, officially the Kingdom of Thailand and formerly known as Siam, is a country at the centre of the Southeast Asian Indochinese peninsula composed of 76 provinces. At 513,120 km2 (198,120 sq mi) and over 68 million people, Thailand is the world's 50th largest country by total area and the 21st-most-populous country. The capital and largest city is Bangkok, a special administrative area. Thailand is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the southern extremity of Myanmar. Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast, and Indonesia and India on the Andaman Sea to the southwest. Although nominally a constitutional monarchy and parliamentary democracy, the most recent coup in 2014 established a de facto military dictatorship.
