Annotated classification of Coleoptera - Britannica.com
There have been a number of different classifications of Coleoptera. Many were based on the suborders Adephaga and
Polyphaga; the latter, which contains about 90 percent of the beetles, included a number of divisions (e.g., clavicorns,
serricorns, lamellicorns, phytophagous beetles, and weevils). Sometimes these divisions are considered as superfamilies
or series, and sometimes (particularly weevils and relatives) as suborders. The classification below is based on that of
R.A. Crowson (1955); it includes four suborders. [eng]

Brown Spruce Longhorn Beetle: A Recently Introduced Tree Pest
The brown spruce longhorn beetle, a relatively innocuous pest throughout much of Europe, has recently gained a toehold in North America. The site of the infestation is Halifax, Nova Scotia where the presence of the beetle has been confirmed in Point Pleasant Park, a lovely 99 acre wooded area in the city's south end. [eng]

Encyclopædia Britannica
Coleopteran: Among the
approximately 250,000 species of Coleoptera are many of the largest and most conspicuous
insects, some of which also have brilliant metallic colours, showy patterns, or striking form. Beetles
can usually be recognized by their two pairs of wings; the front pair is modified into horny covers
(elytra) that hide the rear pair and most of the abdomen and usually meet down the back in a
straight line. Coleoptera occur in nearly all climates. They may be divided into four groups: the first
three, the Archostemata, the Adephaga, and the Myxophaga, contain relatively few families; the
majority of beetles are placed in the fourth group, the Polyphaga. [eng]
