When we think of creatures roosting or going to roost at night, we usually think of birds – one magnificent example is the murmurations performed by Starlings before they all fly down to roost together, or you may have seen photos of mass gatherings of Pied wagtails roosting together for warmth during the colder winter months.

However, birds aren’t the only creatures that roost – some butterfly species also roost at night, or earlier, if the weather is particularly dull and grey. One such species is the Common blue, which roosts, with head pointed downwards, usually on a tall stem of grass.

These photos were taken late last Friday afternoon, following a morning of rain, when the cloud cover was still low and quite dense. The butterflies had obviously given up on the prospect of more sun that day and gone to bed early. I’m sure we all know that feeling!
