Yes
Lady bugs, like most bugs, hatch from eggs.
A larva,then a caterpillar, then it goes into the cocoon, and finally into a beautiful butterfly.
Mantis babies, or nymphs, do not stay in a cocoon; instead, they hatch from an egg case called an ootheca. The eggs typically take about 3 to 6 weeks to hatch, depending on environmental conditions such as temperature and humidity. Once they hatch, the nymphs emerge fully formed and ready to begin their independent life.
No, birds lay eggs and their chicks hats from these eggs. Humming Birds are birds (it says so in their name) so they hatch from eggs.
The type of leech that lives in an oval cocoon is a freshwater leech. These leeches create oval cocoons to lay their eggs and protect them until they hatch.
Theoretically yes - provided the correct temperature and humidity levels are met.
A cocoon is typically considered alive if it shows signs of movement or activity such as fluttering, twitching, or shaking. If the cocoon appears dried out, discolored, or has an unpleasant odor, it may be a sign that the insect inside has died.
All butterfly and moth wings are damp when they hatch from their crysalis. If the interior of the crysalis was dry, they'd die. They need the moisture to keep supple; on hatching they gradually spread their wings until they become dry enough to fly.
Butterflies actually have transform in a Chrysalis rather than cocoon. It takes seven to ten days later the monarch pushes open the chrysalis. The difference in time depends on temperature. Metamorphis occurs more quickly in warmer climates.
They lay eggs on Brassicas and their caterpillars will hatch and eat the leaves. Eventually, the caterpillar will spin a cocoon from inside which an adult butterfly will emerge.
They pull them selves out with there two front legs called shoobers.
The species you are referring to is likely the Polyphemus moth, which spins a white, papery cocoon that resembles cotton. This species is native to North America and belongs to the silk moth family. The cocoon is usually found hanging from tree branches or other structures.
