Anomala orientalis
species of beetle

Anomala orientalis (synonym Exomala orientalis), also known as the oriental beetle (OB), is a species of Rutelinae (shining leaf chafers) in the family Scarabaeidae. It is a beetle about 0.7 - 1.1 cm (0.3 - 0.4 inches) long, with mottled, metallic brown- and black-colored elytra and a similarly colored thorax and head during the adult stage. It is sometimes confused with the larger and more colorful Japanese beetle. During the larval stage, the oriental beetle can be identified by the parallel line raster pattern.
This species is native to Asia where it was first found in Japan in 1875. Over time, A. orientalis was spread to other parts of Asia, including Korea, and has since spread to the United States. It was first found in Hawaii and further spread to Northeast states (such as Connecticut, Maine, and New York) as well as some southern states (North Carolina).
Oriental beetles are notorious for their role as pests on plants ranging from sugarcane and other crops (such as maize and pineapple). As larvae, these beetles burrow into the ground as they move throughout fields and chew through plant roots. Their infestation proves to be a current problem that pesticides are aiming to target.
This brief starts where responsible research should: with the source description of “Anomala orientalis” as species of beetle. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of beetle. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q7102384. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1875.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
