    Metamorphosis: the very hungry caterpillar hits puberty (by Bernie Hobbs)

    It’s not surprising that we don’t tell kids what really happens to caterpillars inside a chrysalis. Metamorphosis is pretty gruesome stuff, involving flesh-dissolving enzymes and limbs, wings and genitals bursting through what’s left of all that tissue. No wonder the whole thing is done behind closed skin.

    Considering the scope of change, it’s amazing that the metamorphosis comes down to the interplay between a couple of hormones and some bags of cells that are just itching to grow into butterfly parts.

    Hello Medusa

    I know these topics have been discussed before – look at the tabs on teh right for disease, dying, emerge, pupa. There’s lots of information here in the forum, I am just strapped for time at present…

    You might be interested in taking the butterfly gardening course we’ve got starting soon… More information here:

    Oh yes, also, why is it that a caterpillar begins to change then stops half way through and appears to just die?

    Hi Jacqui, is it usual for rather small caterpillars to metamorph? I have found one today that has J’d under a leaf and it is half the size of the normal J’s.
