Your letter to the bugman: My mom and I found this caterpillar among her milkweed plants. She raises monarch butterflies, but this one is new. Neither of us have ever seen this kind of caterpillar before.
It was found July 6th, 2020, at around 3:15 PM.

The Monarch is not the only Milkweed Butterfly in the genus Danaus that is found in Texas. We believe your caterpillar is that of the related Queen Butterfly, Danaus gilippus, which is pictured on BugGuide. Queen Caterpillars look similar to Monarch Caterpillars, but they have an additional set of “tentacles” and you were quite astute to observe this difference.
