Monarch butterfly predators include scrub jays, brown thrashers, sparrows, black-headed grosbeak, cardinals, pinyon jays, robins, orioles, and grackles. While most birds are not aware of the butterfly’s toxic parts, some have lately developed methods to prevent eating parts that contain glycoside. The oriole is one of them.

What bugs are attacking monarch caterpillars?
Young instar predatory stink bugs (shield or soldier bugs), were making a move on my monarch caterpillars. These pests attack much lager prey, like my caterpillars, by injecting them with a jab or toxic saliva before sucking on their innards. Nasty jerks. Mine appeared to be Schellenberg’s soldier bugs, a NZ native. Numbers were, fortunately, small. I’ve been inspecting the swan plants regularly and squashing any if found.
Why do butterflies need netting?
Because the netting also prevents butterfly access, eggs and/or caterpillars must be relocated into the enclosure. It also necessitates regular housekeeping, including cleaning up after our messy guests and pruning plants to maintain a suitable size for the enclosure.
Is paper wasp a good pest?
Yes, wasps can be beneficial, but here in NZ they are considered an invasive pest. The Department of Conservation and most local and regional councils actively encourage wasp control. Unlike common or German wasps, paper wasps seek live prey so the usual baiting wasp control use by authorities don’t work.

What are the enemies of monarch butterflies?
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. Some parasites that kill monarchs are insects themselves; these are called parasitoids. Other parasites are extremely small and can only be seen with a microscope. Just like humans, monarchs can get ill or die from diseases caused by parasitic bacteria, viruses, fungi, and protozoans.
How many tachinid fly larvae can a monarch have?
A single monarch can host 8 or more tachinid fly larvae (photo by S. Altizer). Tachinid flies commonly feed on and kill monarchs. These parasitoids lay their eggs on monarch caterpillars. Tachinid fly larvae feed from inside the caterpillar, but usually don’t kill the host until just before the caterpillar pupates.

Parasitoids. Parasitoids are insects that parasitize other insects. Parasitoids such as small flies and wasps lay eggs on other insects and eventually kill their host. Parasitoid larvae eat their host from the inside out, usually emerging from the remains of the host once it becomes a pupa or adult. .

Can coffee grounds stop ants from eating milkweed?
Since the coffee grounds didn’t seem to stop the ants from invading the milkweed plants, I resorted to ant bait traps. We’ve had good luck with the Terro Liquid Ant Baits inside the house so I decided to try their outdoor Liquid Ant Bait Stakes.

How are monarch spores spread?
The spores are scattered by infected adult Monarchs and can also be spread by mating and casual contact. The spore is passed from one Monarch generation to another by the caterpillar eating milkweed exposed to infected Monarchs and is also passed from the female to the egg shell while laying the eggs.
How do tachinids parasitize butterflies?
Tachinids parasitize butterflies by laying eggs on the caterpillar larva. After the eggs hatch the tachinid larva bores into the butterfly larva and completes its development inside the new host. During the Monarchs late instar or pupa stage the fly maggot will drop out on tendrils looking like white strings.
What do caterpillars eat?
When the caterpillar breaks out of the egg and eats the shell it ingests the spores, which reproduce in its body. Caterpillars also eat the spores scattered on the milkweed. During digestion the spores open and release the protozoa, which reproduce.

The monarch butterfly, Danaus plexippus, is found in North America. Its habitats include empty lots, roadsides, wet meadows, gardens, marshes, pastures, and open areas. In other words, it shares the same habitat as the milkweed plant.
What Do They Eat?
Milkweed is a staple of the monarch caterpillar’s diet, to the point where it and its cousins are called milkweed butterflies. The butterfly’s life cycle begins when the female carefully lays her eggs on a leaf of the plant, one at a time, securing them with a bit of natural glue. Other than that she doesn’t provide any parental care.
How to Raise Them
Raising monarchs is easy and fun. Not only this, it benefits the butterflies, whose conservation status is near threatened. They have even been successfully raised aboard the International Space Station.
