Study Notes
Insect Diversity
- There are approximately 400,000 known species of beetles (Order Coleoptera), which have thick wings that meet in a straight line down their back and use chewing to obtain food.
- Butterflies and moths (Order Lepidoptera) make up around 150,000 known species, with four large, scaled wings, and use siphoning to obtain food.
Taxonomy
- Taxonomy is the science of naming, describing, and classifying living organisms, including plants, based on behavioral, genetic, and biochemical variations.
- Classification is based on the characterization, identification, and classification of organisms into groups with similar characteristics, which are categorized into species.
- The Linnaeus classification system, with some modifications, is widely used to classify living beings.
Animal Taxonomy
- Animal taxonomy involves identifying, classifying, and naming animals, using the Linnaeus classification system.
- Animals are divided into two main categories: vertebrates (mammals, birds, reptiles, fish, and amphibians) and invertebrates (arthropods, mollusks, and annelids).
Linnaeus Classification System
- Linnaeus classified the universe into three broad kingdoms: animals, plants, and minerals, and divided kingdoms into classes, orders, genera, and species.
Entomology Taxonomy
- Taxonomists in entomology study organisms and identify them based on their characteristics, such as visible morphological characteristics or genetic differences.
- The Class Hexapoda (insects) is studied under a classification system with approximately 30 orders, many of which are of minor importance and are studied mainly for scientific interest.
Insect Orders
- Insects are classified into 30 groups called orders, based on the shape of their body, legs, mouthparts, and wings.
- The principles of classification of insects involve placing them into different taxonomical categories, including phylum, class, order, family, genus, and species.
Largest Insect Order
- The largest insect order is Coleoptera (beetles and weevils), representing about 40% of known insect species, with around 400,000 known species.
Second-Largest Insect Order
- The second-largest insect order is Lepidoptera (butterflies and moths), with approximately 150,000 known species.
