    UK Status

    An infrequent find in Britain, it is quite likely that Cordyceps militaris is more common than it seems. Despite its bright colouring, Scarlet Caterpillarclub is but difficult to spot, because the clubs are usually much shorter than the grass or moss among which they are growing.

    VC55 Status

    Occasional in Leicestershire and Rutland.
