Life Cycle of Gerris thoracicus
Egg The eggs of gerris thoracicus are typically laid on vegetation near water surfaces. The development within the egg is highly dependent on the surrounding temperature and humidity.
Nymph Nymphs of gerris thoracicus resemble smaller versions of the adult without developed wings. They molt several times, each time increasing in size and gradually developing wing pads.
Adult Adult gerris thoracicuss have fully developed wings and can reproduce. Their elongated bodies and water-repellent legs enable them to skate across water surfaces, where they hunt and mate.

Habitat Preferences of Gerris thoracicus Through Different Life Stages
The eggs of gerris thoracicus are typically found on vegetation submerged in freshwater bodies like streams, ponds, or lakes. Nymphs, resembling miniaturized adults but lacking fully developed wings, inhabit the water's surface tension, skimming across in search of food. Adults share this habitat preference, commonly spotted gliding on the surface of calm or slow-moving water. To locate the different growth stages, search along the edges of freshwater locations for eggs on plants, while nymphs and adults are best sought by silently observing the water surface, focusing on areas undisturbed by strong currents or wind.
