Termites are excellent but only last about 24 hours out of the nest. They need high humidity. Clip the wings of the flies. A jar lid with a little red wine or vinegar of some fermenting fruit will attract tiny vinegar flies. If you place them in a shallow saucer of water they cannot fly but the froglets can still eat them. Insects can be cooled in the fridge (not freezer) for 10 to 15 minutes to slow them down so you can clip wings or remove jumping legs. You usually have a window of around 5 minutes before they start to warm up and become active again.
Maggots are good and can be collected by hanging a fish head or off meat over a bucket with an inch of bran in it. Give the maggots 2 days in the bran or pollard (even better) to clean out their gut contents. When dusted with calcium supplement, maggots cannot crawl out of a vertical sided dish. Fruit fly maggots can be extracted from rotting or over ripe fruit that has not been sprayed. Just a quick rinse in water and a dusting and they are ready to go.
You can often find heaps of aphids on rose buds that can be shaken onto a white plate or saucer. If you have circular bites missing out of the leaves of the roses or other plants, look for the looper caterpillars that are responsible. Small ones will be eaten with relish. You can often find amphipods under flat rocks or sheets of material in the shade in moist places. They jump around very quickly so have the dust pan, broom and bucket at the ready. They need to be kept slightly moist. Daddy Longlegs spiders can often be found in the corners of room, beside cupboards and up under corners of shelves etc. Cool and trim the legs by half or so. Small sized earthworms from a worm farm or compost heap or even rich garden soil that is kept constantly moist. Small slaters from underneath and in the bottom of potted plants.
