Their mother laid eggs within the leaf’s layers. They can’t leave and depend on it for food and shelter
by keeping bits of dead leaves alive in autumn, they increase their window of reproduction into seasons where food is scarce

And since their whole life depends on eating leaf tissue, some plants “pretend to be ill” to avoid leaf mining insects depositing their eggs
Like this Caladium steudneriifolium whose leaves already “ appear”infested with larvae
