I have no idea what these are but today they're everywhere.

Did a little research.
Species Chauliognathus marginatus - Margined Leatherwing
The soldier beetles, Cantharidae, are relatively soft-bodied, straight-sided beetles, related to the Lampyridae or firefly family, but unable to produce light. They are cosmopolitan in distribution. One common British species is bright red, reminding people of the red coats of soldiers, hence the common name. A secondary common name is leatherwing, obtained from the texture of the wing covers.
Soldier beetles are highly desired by gardeners as biological control agents of a number of pest insects. The larvae tend to be dark brown or gray, slender and wormlike with a rippled appearance due to pronounced segmentation. They consume grasshopper eggs, aphids, caterpillars and other soft bodied insects, most of which are pests.
