The caterpillar is the only stage that can 'get' OE. The spore may be on its egg shell or on a leaf that it eats. Once the caterpillar eats a microscopic spore, it has become infected with OE.
Also asked, what causes OE in monarchs?
Ophryocystis elektroscirrha (OE) is a debilitating protozoan parasite that infects monarchs. When dormant spores are scattered onto eggs or milkweed leaves by infected adults, monarch larvae consume the spores, and these parasites then replicate inside the larvae and pupae.
Likewise, what is OE parasite? Ophryocystis elektroscirrha (sometimes abbreviated OE or O.e.) is an obligate, neogregarine protozoan parasite that infects monarch (Danaus plexippus) and queen (Danaus gilippus) butterflies. There are no other known hosts.
Also know, do swallowtail caterpillars need water?
Provide plenty of food to help your caterpillar grow and develop. Feed Queen Anne's lace, parsley and fennel. Keep plant leaves in water to prevent them from drying out. As your caterpillar grows offer fresh leaves three or four times per day.
How do you kill OE?
A solution made of 10% bleach and 90% water will kill OE spores. To sanitize the milkweed, completely saturate the plants with the solution, let the bleach work for five minutes, and then rinse the milkweed several times in clean water. Allow the milkweed to dry before feeding it to the caterpillars.
What is butterfly OE?
OE (Ophryocystis elektroscirrha) is a protozoan parasite that infects butterflies in the Danaus species group, those that host on milkweed. In the US, Monarch (Danaus plexippus), Queen (Danaus gilippus), and Soldier (Danaus eresimus) butterflies are affected by OE.What causes OE?
OE is a protozoan parasite that caterpillars ingest on milkweed. It's spread through microscopic spores coming off the wings and bodies of adult butterflies. These protozoa multiply inside the caterpillar and can cause weakness, disfigurement, and an untimely death.Do butterflies remember being caterpillars?
The study showed that memory, and therefore the nervous system, stays during the complex transformation from the caterpillar to the adult moth. So while a moth or butterfly may not remember being a caterpillar, it can remember experiences it learned as a caterpillar.Is my caterpillar dead in its cocoon?

| Caterpillar (larval) stage | 3 to 4 weeks |
| Chrysalis (pupal) stage | 10 to 20 days (except for overwintering pupae) |
| Adult butterfly stage | 6 to 14 days |
How big does a swallowtail caterpillar get?

- Go over to a yard waste can and cut off the thorns on the part of the stem that will be submerged in water.
- Put the cuttings inside the caterpillar cage.
