Perfect for transport

My butterfly nursery is in an upstairs bedroom. When it's time to release a monarch, I use this little cage to safely transport my newbies downstairs and outside!

Butterfly ER cage

Great size for transporting butterflies out to the garden. Helps avoid disrupting the others. Also great if you have a fallen chrysalis. When you see they are about to emerge, transfer them to the ER cage so the can come out and dry undisturbed. Great little cage.

Perfect For a Holding Spot

This little enclosure is perfect for keeping a new caterpillar isolated, and for keeping a newly eclosed Swallowtail until release. Very happy I found these!

Monarch ER butterfly cage

Good for hatching a detached chrysalis!
