I am fairly certain this is a Laphria sericea (male) I would like to know what the white circular object is at the base of the hind legs? I saw this same thing on other photos on BG.

Please correct or confirm my ID,

Thanks,

The circular thing at the
base of the wing is the haltere, a kind of balancing organ that true flies (Diptera) have instead of hind wings.
