Silkworm moth eggs.

In case you are wondering, the female moth in the top photograph laid her eggs on a paper towel. The female in the bottom photograph laid on a cardboard egg carton.

    how did you get the eggs off of the cartons and the paper towels? we (my daughter and i) have tons of eggs, but i want to put them in the fridge to create a false winter so that they will hatch later… any ideas are appreciated! šŸ™‚

    Congratulations on the eggs.

    We didn’t take the eggs off, we simply cut the cartons and towels into manageable-sized pieces. Anyone else have any ideas?

    Could you be a bit more specific? Do you want to know about their life cycles or how to identify them?

    My kidz have silkworm eggs and they did not hatch jet. [21 sept 2016] how long do they have 2 wait.

    When they will hatch will depend on several factors. Did you buy them pre-conditioned? Did they come with any instructions?

    Insect eggs are sensitive to temperature. Cooler temperatures slow things down, higher temperatures speed things up.
