Surprise visitor joins monarch butterfly in the garden

The monarch butterfly gathering nectar in this photo and in the following video wasn't in a hurry to get the job done.

Although the butterfly stayed on just one bloom of cutleaf coneflower the entire time, it moved around extensively.

While it was sipping sweet nectar with its unfurled proboscis, another critter was also in the garden.  Watch the video to find out who the surprise visitor is.
