There are lots of common red soldier beetles (Rhagonycha fulva) around. Fortunately there are also lots of aphids, a favourite source of food.
All the soldier beetles are clumsy fliers; like ladybirds, they take off from the highest point they can reach and land apparently haphazardly. At this time of year, if a flying beetle lands on you, it is almost bound to be a common soldier beetle. Don’t be alarmed; it is harmless.
