The image of a solitary beetle on a blossom is definitely a Blister Beetle in the family Meloidae, but we are uncertain of the species. The other image showing an aggregation of Beetles appears to be a different species. Can you clarify any information on these two images, especially the group of beetles. Were they found aggregating as the image depicts? Here is a BugGuide image of Linsleya sphaericollis that resembles the Blister Beetle in your image of a solitary individual, but again, we cannot verify the species.
