Keep your pupae safe from cannibalistic larvae and beetles with these new Pupae Bridges. Made from 1/8in laser cut material, these Pupae Bridges are elevated off the substrate and provide lots of dark space below. Simply insert the bridge into your beetle or larvae tray, pick out your pupae, and spread them out on the flat surface of the bridge. When the beetles emerge they will crawl off the bridge and down into the substrate to join their friends! To prevent the hungry cannibals from climbing up to eat the pupae buffet, you can apply packing tape to the sides of the wooden bridge supports.
