Larviform Females

Larviforms are ladies who remain forever young –
As they climb-up through the instars but won’t reach the highest rung.
So they stay as grubs or maggots or as caterpillar bags,
Where these slow and wingless-women are such lazy lallygags.
Most will still pupate, but then emerge as they went in –
Or at least upon the outside, though their innards had a spin.
So they still have genes for adult-forms they’ll never get to wear,
But they do tend to be larger than the chaps, so plusses there.
I guess it works for them, as long as blokes can come and find them,
And they get on with the job that evolution has assigned them.
So they’ll never get to fly, but still their shells are looking smart –
Maybe larviforms are ladies who are just big kids at heart.

Larviforms are a kind of neoteny, which I’ve discussed before.
