SLEEVES for REARING LARVAE

Sleeves are a great aid for rearing Lepidoptera.  Sizes are approximate.

On growing foodplant sleeves enable a constant source of fresh food, and for periods away on holiday larvae can be left unattended for days. The sleeve can be on a bush or tree outside, or it can be slipped over a potted plant.  As well as providing fresh food, the larvae are prevented from wandering, and they are protected from predators and parasites.

Sleeves can be a useful substitute for cages, and much less costly. You can often rear larvae on cut food contained in a sleeve, as long as the foodplant is changed before it loses its freshness.

The sleeve is slipped over a branch or plant and both ends are secured to prevent escape. Our sleeves are hand sewn using black material which gives excellent visibility.

The mesh is fine. The netting is strong and durable – suitable for use throughout a winter for hibernating larvae. Click the View button to see tips on using sleeves and diagram of sizes.

NEW Bag Sleeve with zip opening for instant access. Large Size 4 70 x 130 cm
Availability: NOW


NEW Bag Sleeve with zip opening for instant access. Large Size 4 70 x 130 cm

This size gives considerable extra space for larger larvae, or increased numbers. The end of the bag is sewn up. The open end is slipped over a branch and tied with string, or better still, the Velcro ties that we recommend in this Sleeve section.

Access from the side zip is not only instant for opening and closing, but you can really get to any part of the sleeved branch. The way is clear for all inspection and maintenance, and frass is instantly removed. You can easily collect semis (fully-developed larvae that are preparing for pupation) ready to go into their puparium. If the larvae are cocoon spinners you can reach all areas when you wish to collect the cocoons. The zip means that you can easily pop a caterpillar back if you find one has crawled on to you while attending to the sleeve. If showing the larvae to family and friends, it's so much better to unzip the side than undo an end, and have to gather and tie it again - simply open the sleeve, with wide access, then instantly zip it up again! 

When you use a Zipped Bag Sleeve you will wonder why it has taken until now to use such an innovation!
