Don't know the real name but we call them sun beetles .... I have quite a few on my English marigolds as well .... Val

Pollen beetles. Lots and lots of people have been asking about them - the beetles must have had favourable weather and a population explosion. They don't do any harm.

As Beattie says, these are Pollen Beetles. The large numbers being reported recently are a result of the warm, dry weather which ensured lots of the larvae made it to adulthood. Theses adults only eat pollen (not the flowers) and are one of the most important groups of pollinators for summer flowers.

Thanx a lot for all your information guys
