This week’s mines can be found on thistles, on species of both Cirsium and Carduus – in my case, the plant is Creeping thistle (Cirsium arvense).

These mines have been made by the larvae of the moth Scrobipalpa acuminatella, the adult of which can be seen on the UK Moths website. As the website points out, these moths have two generations each year, so we get two chances to see the mines.

These moth larvae make their home in the midribs of thistle leaves, venturing out to eat during the night and making blotches as they do, then returning to the midrib to shelter during the daytime.
