Dogbane is a plant that so strongly resembles milkweed that many people, including those experienced in the field, can be fooled it it. Monarch caterpillars will not eat it.
Dogbane is on the left Milkweed is on the right Monarch host plant
Dogbane is related to milkweed and the Milkweed Tussock Moth (actually a tiger moth but more often called tussock moth) will eat it.
Dogbane also has white sap that can harm eyes, making it even more difficult to tell them apart. Click on this sentence to learn how to tell them apart.

It’s cold out there. It’s too cold for butterflies to fly, caterpillars to crawl, chrysalises to emerge, or eggs to hatch. So where are butterflies and moths?
Simple! Many are right there in your garden, right in front of your eyes.

We’re delighted that ‘Monarch Promise’ was released this spring. Every time we see it, we are struck all over again with its beauty.
Monarch Promise Milkweed
Supplies are limited, we discovered. The wholesale nursery that has the rights to sell wholesale to other nurseries is sold out. If you see any, buy them before it is too late!
Because the plant is patented, it can only be propagated by one nursery (besides ourselves). This means that more won’t be available until this fall.

Why can’t we remove OE from nature once and for all? Ophryocystis elektroscirrha is here to stay?
OE spores Monarch butterfly
There are several reasons:
1) it is estimated that at least 1/3 of Monarchs in the US have OE to one degree or another
2) all Monarchs in the Miami/Dade area are considered infected with OE
3) most likely nearly all Monarchs in Mexico are infected with OE
4) the parasite is found in many countries and several continents and islands
5) Queens in the US and Mexico (at least) are infected with OE
6) OE will transmit from one species to another
7) OE has been found in 3 Danaus species and suspected to be in more
8) Millions of Monarchs from the Eastern US, Eastern Canada, and some from the Western US migrate to Mexico, intermingling with each other during winter months. Many are OE infected. When they begin to mate in the spring, one without OE will often mate with one with OE. This will transfer spores to the outside of the uninfected butterfly where they can be transferred to milkweed leaves, another Monarch, and milkweed leaves. (Cross-transfer causes few problems compared to direct infection.)

Can you tell which is which? If you find these two chrysalises, or just one of them, will you know what species of butterfly you found?
Eastern Tiger Swallowtail
The good news is that it really doesn’t matter. Either leave it where you found it or take it home and care for it and allow it to emerge and release it. You’ll find out what it is when it emerges.
For some of us, we aren’t that patient. We want to know NOW.
In this case, the chrysalis on the left is an Eastern Tiger Swallowtail and the chrysalis on the right is a Black Swallowtail. But be aware; there are other species that become chrysalises that are similar in appearance.
