All cicadas go through an interesting 3-stage life cycle : egg, nymph and adult. Females lay many eggs in tree barks sliced open by her sword-like ovipositor. The tree bark protects the eggs until they hatch into nymphs. The wingless nymphs burrow underground . Once they mature, they dig themselves out from the soil, creating mud chimney during rainy days.
Though I didn't encounter many flying jewels in our forest in this outing, I was glad to meet some old and new members of BC.
