These ship every Monday. In order to have shipping on the upcoming Monday, please get your order in by Thursday at noon.

Included: 30 mixed size Porcellio laevis, our composting isopod, and full instructions. You'll recieve a mix of juvenile and adult; this is our smaller kit size.

The isopods come housed in a shipping container and will need to be rehoused in 1-2 weeks. Additional substrate and housing not included. 

Our P. laevis are what is called "wild-type," and get comparatively large (2 cm in length). They are an excellent composting resource: we call them our charismatic composters. They are easy to feed and care for, consuming a large amount of exotic human vegetable and fruit scraps, vividly interesting, and do not bite, smell, fly or jump.  They can be housed in everything from a recycled deli container to an aquarium.  The cohabitate wonderfully into a red wiggler container composter, and when combined this way prove more efficient than worms on their own - though the compost they produce is not as clean. They do not climb smooth surfaces such as plastic or glass. 

Isopods are a fantastic and easy colony organism in the classroom - not insects, but tiny land crustaeans which breathe through gills - with many uses. As an in-home or in-classroom composter, they eat common household veggies and fruits like apple cores, cucumber, carrot, squash, and lettuce. They are relatively tolerant of disturbance and prefer soil and soil-like material for bedding (coconut coir, peat, black earth, decaying wood chips). Isopods are also a great beneficial member of your reptile or amphibian vivarium, as they will clean up waste products produced by your other pets. These are a must-have addition to a Waste in Our World unit, because unlike worms, kids can handle isopods.

Isopods cannot be released outdoors.

Isopods can be ordered year-round.


Replacement only: no refunds. We have an "arrive alive" guarantee but we cannot guarantee the well-being of the animals past shipping: once they are in your hands, you must be prepared to care for them. Simple instructions will be included with your order, which can be supplemented with research of your own. Remember: you are dealing with living animals who will be reliant on you. Nature is not perfect; in the wild, survival rates would naturally be very low in arthropods. In captivity, you should expect a much higher rate of 70%-90% survival. Please incorporate these statistics into your lesson plan, and never assign a single isopod to a single participant, as some of them will not make it. It is always ideal to observe invertebrates as a population.

SHIPPING: Please review your invoice carefully to ensure there are no mistakes in the information we have been given for you. Ensure your order has been translated correctly. Butterfly Wings N' Wishes is not responsible for shipment delay or failure due to incorrect information on the invoice. If an order is delivered to an incorrect location or is returned to us due to these issues, we may charge an adjustment fee in event that your parcel's delivery must be corrected.

Incomplete orders (missing phone numbers, missing physical address, etc) will be cancelled and refunded. PO boxes are not valid addresses.

If you want separate shipping dates, separate orders must be placed to account for the separate shipping fees: otherwise we will default you to a single shipment at the convenience of the animals.
