How many Coleoptera familys are there?
More than 200 families of extant and extinct beetles are known. Although there are different classifications of Coleoptera, modern systems are based on the four suborders Adephaga, Archostemata, Myxophaga, and Polyphaga.
What family is Coleoptera in?
beetles
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. Boll weevil (Anthonomus grandis).

The extraordinary diversity of beetles (order Coleoptera; >400,000 species) has been attributed chiefly to the adaptive radiation of specialized herbivorous beetles feeding on flowering plants (angiosperms) (1–4).

Are Coleoptera Staphylinidae aquatic or semiaquatic?
Notes:The shorted elytra will separate these beetles from other aquatic and semiaquatic Coleoptera. The family Staphylinidae is a large family, but the majority of the members are terrestrial. The staphylinid species considered aquatic or semiaquatic do not occur beneath the water surface. Figure 12.81: Scirtes sp. (Scirtidae) larva, Dorsal View.
How many segmented legs does a Coleoptera have?
In addition, the entire body is generally hardened and three pairs of segmented legs are present. Adult Coleoptera families can be separated by characters such as the shape of the eye, the hind coxae, and the antennae (Figure 12.3, Figure 12.2,).
How can you tell a Coleoptera from an adult?
COLEOPTERA Adults: Coleoptera adults can be recognized primarily by the presence of heavily sclerotized fore wings (elytra) which lack veins and cover the membranous hind wings (Figure 12.2). In addition, the entire body is generally hardened and three pairs of segmented legs are present.
