How do you keep wasps from killing monarch caterpillars?
A good way to deter wasps is by placing 5 Gallon Paint Strainers or Mosquito Netting over your milkweed. You can use tomato cages for extra support. This will keep them from snatching up your poor, unsuspecting caterpillars. This idea works best for potted milkweed plants.
How do I know if my caterpillar has parasites?
Your caterpillars may become lethargic, shrivel up, have something runny come out of either end and turn black. Sometimes they will pupate, start to get dark but the wings aren’t visible, they just turn a brownish black. Sometimes they will start to pupate then turn to black goo.
Do paper wasps eat monarch caterpillars?

What is killing my monarch caterpillars?
Predators such as spiders and fire ants kill and eat monarch eggs and caterpillars. Some birds and wasps feed on adult butterflies. These predators are easy to see, but monarchs also suffer attacks from parasites, organisms that live inside the monarchs’ bodies.
What do wasps do to monarch caterpillars?

What if monarch caterpillars run out of milkweed?
Running out of milkweed leaves this time of year is NORMAL. This is natures way of insuring fresh leaves for the next generation. This is the most important generation as it will migrate to Mexico. You WILL have some caterpillars that will turn to chrysalis.
How do monarch caterpillars get parasites?
Infected females pass on the parasite to their offspring when they lay eggs by scattering dormant spores on their eggs and the surrounding milkweed. When a caterpillar hatches, it not only eats its egg shell and the milkweed, but also the OE spores. Once eaten, the dormant spores move into the caterpillar’s midgut.
What percentage of monarch caterpillars survive?
If you follow basic principles of cleanliness, your monarchs’ survival rate is likely to reach 80-95%, far exceeding the meager 2-10% of monarchs that survive to become butterflies in the wild. It’s important to remove the caterpillars’ poop (called frass) from their dwelling at least once a day.
Can you touch monarch caterpillars?
It is safe for humans to hold and touch the Monarch caterpillar but it is not always safe for the caterpillar. When they are young/small they are quite delicate but as they grow it becomes safer for them to be handled. The one time that no caterpillar should be handled is when they are preparing to molt.
Can monarch caterpillars survive on milkweed stems?
Monarch larvae will feed on all commonly available milkweed species (but do not confuse these with other plant species with a milky sap). Milkweed plants can be collected in the field (cut stems) and stored in a refrigerator in plastic bags for 4-5 days. Leaves should be rinsed and dried before feeding.
