Caterpillar Setups > Netted sleeve

Cuttings of some species of trees may not necessarily keep well in an open terrarium or open bucket type setup.

An alternative is to create a pull-string nylon net sleeve and place this around a branch with caterpillars. This also saves the time of cleaning out frass and changing out host plant cuttings.

The drawback to this technique is that spiders can smell caterpillar frass and still kill butterfly caterpillars if they are too close to the sleeve. Parasites are also a major concern. Make sure that the sleeve is completely secure from predators or parasites that can enter and kill your larvae.  See this video.
