I did not realize monarchs were still being hatched in the fall. This pic was at NYBG and saw another at the Farm last week. Thanks all

Monarch caterpillar and milkweed bugs enjoying a meal?
Here is even more info on insects that feed on milkweed.

The milkweed aphids (Aphis nerii)and a monarch caterpillar are pigging out on milkweed. If you’re trying to nursemaid a caterpillar, these guys eat about 10 of those big leaves a day. That’s why you have to plant lots of them!
The milkweed aphids are also called oleander aphids. Down south, the oleanders are very prolific. They have a similar milky poisonous sap. I’ve never seen a monarch caterpillar on them, however.
