Monarch Being Chased by Silvery Checkerspot

[Mona Miller]

Yesterday I saw a Silvery Checkerspot chasing a Monarch. Was it a male Silvery Checkerspot chasing a female Monarch? I didn't get the male/female on the Monarch identified, but I couldn't figure out why a small butterfly would be chasing a large butterfly.

This is the Silvery Checkerspot:
