- 💡 The adult body length of 35–45 mm is about half the width of a credit card (85.6 mm) (Comparison).
- 💡 The larva, called an 'antlion,' digs a mortar-shaped pit in dry sandy soil and waits for ants to tumble in.
- 💡 Japanese sources note that the pits of larvae in this group can be found in dry soil beneath the floors of buildings, temples, and shrines.

📖 1. Overview
Hagenomyia micans is an insect in the family Myrmeleontidae. Adults resemble damselflies or dragonflies but have prominent antennae, while the larvae are known as 'antlions' that dig funnel-shaped pits in sandy ground.
🦴 2. Anatomy & Morphology
Adults are 35–45 mm long with slender bodies and four transparent wings covered in a net-like mesh of black veins.
🔍 3. Ecology & Behavior
Females insert the abdomen into dry soil—such as beneath building floors or under overhanging cliffs—to lay eggs one by one. The larva digs a mortar-shaped pit in the ground, hides at the bottom to catch falling ants or small insects, and spends 2–3 years mainly in the soil before adults emerge from June to October.
