It ranges between a black and an aqua-marine/ lime green. Normal color your not pregnant.
That's normal. Ladybugs are entirely black save for their elytra (shields).
Go and see a doctor urgently.
A black freckle is normal. Just be sure to watch it over the next few months to see if the shape, size, or color changes. If it does then I would consult with your doctor.
Nothing! It's completely normal, it can be any colour from red to black, or even a mixture! Hope i helped :)
It depends on what you feed them. They can be anywhere from light brown, through to black.
