Insects that need wings have to go through metamorphosis to get them.
The larval stage never has wings,
No. They hatch from eggs and grow.
ants grow at the speed of half a cm every month
Horses do not go through metamorphosis, they do not change form when they grow. That is only for insects and amphibians.
Koalas do not shed their fur to any great extent. During the year, they undergo a gradual moult, but they do not undergo any significant moult as they grow, nor any particular seasonal moult.
They grow lungs, and lose their gills.

Yes - all insects go through metamorphosis. I'm not sure if crickets go through complete metamorphosis the way butterflies and most insects do. Their close relatives, grasshoppers and katydids, are some of the only insects that do not go through complete metamorphosis. Instead, they shed a few times until they reach their adult form. Either way, crickets do go through metamorphosis.
Incomplete metamorphosis involves the animal slowly growing larger through successive moults. The young are called nymphs, and their wings grow externally (like buds) in the early instars. (Eg. grasshoppers, cicadas,etc.) Complete metamorphosis involves separate stages of development; larvae, pupa and adult. (About 90% of insects, including butterflies)
Its juvenile stage looks just like the adult, but smaller and wingless. It molts to grow, and in the final molt the wings fully develop (instead of pupating into the adult form). Insects that do this include dragon/damselflies, mayflies, grasshoppers, cockroaches, mantises, aphids, cicadas and true bugs (Hemiptera).
Are you mental? No they can't grow wings.
No, we can't grow wings.
