Tips for rearing leaf-miners and gallers
Brilliant help provided by @ceiseman on his blog:

These tips are for northern climes, so you will need to adjust some things for our southern conditions. Probably best not to put them in the fridge, for example. Also, in the winter-rainfall area especially, many insects emerge in winter, so you'll need to keep an eye on them.
I have found humidity in rearing containers in the western drylands to be a festival of mould and death. But humidity is definitely required for at least some beasties in the east.
You will need to experiment obviously, and Charley's blog is an excellent base to work from.
Happy rearing :-)
