I do. Generally, I will try and breed the adult if it is permitted. Some caterpillars are more distinctive than adults for instance you can separate Grey and Dark Daggers as caterpillars but not adults (save for dissection) and you can only be really confident separating Narrow-bordered and Five-spot Burnets as caterpillars. I've also helped out on larval surveys on species that I wanted to see.
Further, some species are also easier to find as larvae. Far easier to see all the British Pugs that way.
There are further complexities. If you collect a Sallow Clearwing gall, would you open it up to see the caterpillar or breed it through and tick the adult.
When I have the time to think about building a moth list, a proper attention to larvae and micros will be on my agenda.
Larvae/occupied leafmines would be added (I believe).
At least two of the amphibians on my lifelist are critters I have only seen in tadpole/egg mass form
