LEGO Ideas The Insect Collection (Set 21342) is a 1,111-piece building set for teens and adults featuring three life-size, highly detailed, posable insect models: a Blue Morpho Butterfly (Morpho peleides), a Hercules Beetle (Dynastes hercules), and a Chinese Mantis (Tenodera sinensis). Each model comes with a buildable natural habitat diorama showcasing organic elements such as bark and foliage, and the set includes bonus miniature creatures — a honeybee, a 7-spotted ladybug, and hidden beetle larvae.

The Blue Morpho Butterfly captures the species' signature shades of blue with adjustable wings and is displayed alongside a buildable flower and honeybee. The Hercules Beetle — the longest beetle in the world — features openable elytra (hard wing casings), detachable hind wings, and the characteristic twin horns of the male. The Chinese Mantis model offers impressive articulation with fully posable limbs and printed compound eyes, accompanied by a 7-spotted ladybug on its habitat base.

The set uses no stickers, instead relying on printed elements and newly recolored sand green pieces for authentic detail. All three insects can be displayed individually or together. Designed for LEGO Insiders and nature enthusiasts, this collectible set was created through the LEGO Ideas fan designer program. Recommended for ages 18 and up. Available at Costco for $64.99 (MSRP $79.99).
