Cynodon dactylon
The larvae feed on Poaceae species, including "Brachypodium distachyon", "Cynodon dactylon", "Ehrharta erecta", "Poa poiformis", "Microlaena stipoides", "Poa tenera" and "Themeda triandra". The common brown butterfly is emerging ten days earlier than it did 65 years ago due to the effects of climate change.
