Insects are a class of invertebrates within the phylum Arthropoda, characterized by a three-part body structure (head, thorax, abdomen), three pairs of jointed legs, compound eyes, and one pair of antennae. They are the most diverse group of animals on Earth, with over a million described species and many more yet to be discovered.
Bangladesh’s diverse ecosystems host a wide range of insects including butterflies, beetles, mosquitoes, bees, ants, and dragonflies. Insects have significant ecological roles and also impact agriculture, health, and livelihoods. Research and conservation efforts focus on beneficial insects and control of harmful pests.
