Found this in sanfelipe Baja mexico, after I woke up with a bite on my are that swelled quickly. Wondering if it could be the cause.

If this is the culprit, you were stung and not bitten. This looks like a Short-Tailed Ichneumon, possibly in the genus Ophion. Most Ichneumons are harmless, but members of the genus Ophion are capable of stinging. According to BugGuide: “Adult Ophion species will hunt for their host caterpillar. Usually one egg is laid per host. Caterpillar usually dies during pupal stage though wasp larva remains to pupate itself.”

Based on a comment we just received that needs considerable research, we are no longer categorizing this an an Ichneumon.
