After posting about the queen caterpillars on our rush milkweeds last week, this week I came across another scene.
Let's take a closer look.
Maybe if you see the caterpillar more closely?
The caterpillar has two pairs of filaments or "tubercles" that look like antennae. That means it is a monarch butterfly caterpillar, Danaus plexippus.
The butterfly is a queen butterfly, Danaus gilippus. The queen caterpillar has three pairs of tubercles and different patterned stripes (see comparison here).
Yes, our milkweeds are busy this year.
