IMPORTANT UPDATE- Oct 9, 2026. This coming Tuesday will likely be our final shipment of eastern monarch caterpillars for 2026. All new orders placed after Oct 13 will be considered pre-orders for the 2027 season, which is expected to start in April or May 2027.
This product is only for customers who live on the EASTERN side of the country, EAST of the continental divide (AKA The Rocky Mountains). You are good to go if you live on the East Coast, the South, or the Midwest! If you live west of the continental divide, you need to order from our WESTERN Monarch Caterpillars page (for Colorado, Montana, New Mexico, and Wyoming, check the maps below for your state. Most people in these states reside on the eastern side of the divide)
These kits are very easy, and perfect to watch 12 monarch caterpillars form a chrysalis. It comes with everything you need. 12 Native Monarch Caterpillars, and
NO MILKWEED REQUIRED- these larvae will be nearly fully grown, so you can watch them form their chrysalis the day or two after they arrive at your door. (you can upgrade to add a few stems of milkweed if you want to watch them feed before they pupate). You can release your 12 adult monarchs outside about 11 days later! This is the highlight of the whole experience!
