Black Rocket Bug

This is a bit of an emergency blip  -  Penny came this morning to talk over her college project  -  'Photographers at Work'!  We were so busy talking photography I forgot my Blip  - unbelievable but true!  It wasn't until she left that I remembered!  Anyway, plucking some rocket for my salad this evening I noticed the rocket flower was covered in these black bugs. I brought the flower indoors and managed to get a few of the bugs to stay around it. The bug is very small  -  about 2mm!  It might be a pollen beetle.
