| Underwing Moth |
Moths with transparent wings that convincingly mimic wasps and bees — the hornet moth looks exactly like a hornet; other species mimic bumblebees or wasps so precisely that even experienced naturalists hesitate; adults are active by day and fly fast; larvae bore in tree trunks, stems, and roots for 2–3 years.
A common name applied to several different long-legged arachnids — including harvestmen (which aren't spiders), cellar spiders, and crane flies (an actual insect) — none of which are dangerous to humans despite persistent myths.
The heaviest insect on Earth — a male goliath beetle in its larval stage can weigh up to 100 grams, more than a small bird; the adults are strikingly patterned in black and white and can reach 110 mm in length; found in the tropical rainforests of Africa, they are popular in the insect-keeping hobby.
A soft-bodied, colourful beetle named for its scarlet-and-black colour reminiscent of a British redcoat soldier — an important pollinator that visits flowers for pollen while hunting smaller insects.
A large nocturnal moth with cryptic gray-brown forewings camouflaged like tree bark, concealing brilliantly colored hindwings flashed in startle displays to confuse predators.
