The most common lacewings are in the green lacewing family, Chrysopidae, and the brown lacewing family, Hemerobiidae. Updates? Generally, the larval stage may last several weeks, and usually requires three instars. Before depositing an egg, the female lacewing produces a long, thin stalk, which she usually attaches to the underside of a leaf. After an hour of inactivity, each larva completely freed itself and rested on its empty egg shell, waiting for its soft, delicate body to harden before venturing out in search of food. Lacewing larvae feed on other soft-bodied insects or arachnids, including aphids, mealybugs, mites, and Lepidoptera eggs. This order of insects frequently includes the snakeflies (Raphidiodea) and the dobsonflies and alderflies (Megaloptera). Announcing our NEW encyclopedia for Kids!

After about two weeks of continuous feeding, the larva spins a silken, pearl-sized cocoon on the underside of a leaf and remains in the pupal case approximately two weeks before emerging as an adult.

I was completely engrossed in photographing the eggs from all possible angles, waiting for the larvae to emerge, but nothing significant happened for another day. The lacewing is also known as a stinkfly because it emits a disagreeable odour as a protective device.
