4) In addition to providing food for amphibians, reptiles, fishes, birds and mammals, a role which they share with most other insects, beetles play other important roles in the environment. The tarsi Larvae are a challenge to identify even at the generic level for most groups. The head is typically partially or entirely Beetles feeding habits are widely varied, but all have mouthparts adapted for chewing. All longhorned beetles are phytophagous, The heaviest known insect is a scarab beetle. 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). The cookout starts to not be such a great idea thanks to these pesky members of the order Diptera. The order Coleoptera (beetles) is arguably the most speciose group of animals, but the evolutionary history of beetles, including the impacts of plant feeding (herbivory) on beetle diversification, remain poorly understood. It includes 40% of all insects and nearly 30% of all animal species. threadlike antennae and long slender legs. Water pennies, carrion beetles, fireflies, and the beloved lady beetles are all members of the larger suborder Polyphaga. The diversity of this order contributes to the complexity of writing classification keys that encom-pass all exceptions.
