Nymph
This is a nymph of the Large Milkweed Bug. "Bug" is a common word for insect, but it also refers to a specific class of insects, the Hemiptera.
"Large" is a relative term. This Large Milkweed Bug nymph was less than 1/2" long (about 13mm). Larva of milkweed bugs develop in stages ("instars") before becoming an adult. These instars are commonly called "nymphs".
Interestingly, adult milkweed bugs migrate south during the winter, and return to Michigan in warmer weather to eat the seeds of my Butterfly (milk-)Weed plants.
There is a picture of an adult "Small Milkweed Bug" in the first comment below.
