Red milkweed beetle
The red milkweed beetle is a bright red beetle with black spots and long black feelers. It lives almost only on milkweed plants. Its feelers grow right through the middle of its eyes, so each eye looks like two.

How fast is it?
Fun facts
Milkweed has poison in it. The beetle keeps some of it in its body, which makes it taste horrible to hungry animals.
Its bright red and black colours are a warning sign that says: I taste bad.
When it gets a fright it makes a squeaky noise, and when it meets another beetle it makes a soft purring sound.
It bites open the veins of a leaf first so it does not get covered in sticky milky sap.
In midsummer the mother lays her eggs inside the bottom of the milkweed stem.
