•     Leafcutter Ant (Atta spp.) – Tropical forests; farms fungus with cut leaves.
•     Stag Beetle (Lucanus spp.) – Found in deciduous woodlands; large mandibles.
•     Bark Beetle (Scolytinae) – Lives under bark; can damage trees.
•     Atlas Moth (Attacus atlas) – Lives in tropical forests of Asia.
•     Stick Insect (Phasmatodea spp.) – Perfectly camouflaged among twigs and leaves.
•     Peacock Butterfly (Aglais io) – Hibernates in forest shelters during winter.

🏜️ 2. Desert Insects

Desert insects are adapted to survive extreme heat and dryness. Many are nocturnal and excellent at conserving water.
Common Desert Insects:

•     Darkling Beetle (Tenebrionidae) – Found in hot deserts like the Sahara and Sonoran.
•     Saharan Silver Ant (Cataglyphis bombycina) – Fastest ant; survives in extreme heat.
•     Desert Locust (Schistocerca gregaria) – Swarms form after rains in desert areas.
•     Velvet Ant (Mutillidae) – Furry, wingless wasp with a painful sting.
•     Palo Verde Root Borer (Derobrachus hovorei) – Giant beetle found in U.S. deserts.

💧 3. Freshwater Insects

These insects either live in water or rely on it during some part of their life cycle (e.g., as larvae).
Common Freshwater Insects:

•     Water Strider (Gerridae) – Skims across the surface using water tension.
•     Diving Beetle (Dytiscidae) – Fast swimmers that hunt other insects underwater.
•     Caddisfly (Trichoptera) – Larvae build protective cases from sand and plant bits.
•     Mosquito (Anopheles, Culex) – Lays eggs in still water.
•     Mayfly (Ephemeroptera) – Larvae live in clean rivers; adults live only 1–2 days.
•     Dragonfly (Anisoptera) – Aquatic larvae (nymphs) are fierce underwater hunters.

🐝 4. Grassland and Savanna Insects

These habitats are home to a variety of fast-moving, sun-loving insects that often rely on flowers or other insects for food.
Common Grassland/Savanna Insects:

•     Monarch Butterfly (Danaus plexippus) – Migrates across North American prairies.
•     Bumblebee (Bombus spp.) – Pollinates wildflowers and crops.
•     Digger Wasp (Sphecidae) – Buries prey in soil nests.
•     Katydid (Tettigoniidae) – Camouflaged among grasses.
•     Grasshopper (Caelifera) – Common in meadows and fields.
•     Tsetse Fly (Glossina spp.) – Lives in African savannas; transmits disease.

🌾 5. Agricultural and Urban Insects

These insects thrive in human environments, including gardens, farms, and cities.
Common Agricultural & Urban Insects:

•     Honeybee (Apis mellifera) – Pollinates crops; raised in hives.
•     Housefly (Musca domestica) – Found near food and waste; spreads bacteria.
•     Corn Earworm Moth (Helicoverpa zea) – A major crop pest.
•     Aphid (Aphidoidea) – Sucks plant sap; often found on crops and flowers.
•     Ladybug (Coccinellidae) – Helpful garden predator; eats aphids.
•     German Cockroach (Blattella germanica) – Urban pest in homes and buildings.

❄️ 6. Cold and Mountain Insects

These insects are specially adapted to survive in cold climates or high altitudes.
Cold Climate Insects:

•     Snow Flea (Hypogastrura nivicola) – Not a true flea; active on snow during winter.
•     Mountain Butterfly (Parnassius spp.) – Lives in alpine meadows and mountains.
•     Arctic Woolly Bear Moth (Gynaephora groenlandica) – Larva can survive freezing temperatures.
•     Glacier Stonefly (Zapada spp.) – Lives near icy streams; sensitive to climate change.

🌲 7. Rainforest Insects

Rainforests have the highest insect diversity in the world due to their warm, wet climate.
Common Rainforest Insects:

•     Blue Morpho Butterfly (Morpho menelaus) – Iridescent wings; found in Amazon.
•     Bullet Ant (Paraponera clavata) – Infamous for its extremely painful sting.
•     Leafcutter Ant (Atta spp.) – Farms fungus inside rainforest colonies.
•     Lanternfly (Fulgora laternaria) – Bright colors and unusual head shape.
•     Harlequin Beetle (Acrocinus longimanus) – Bright patterns and long forelegs.
