I was just reading through science daily and I came across the sad news that there is a steady loss of butterfly species due to a variety of factors. These butterfly species are habitat specialists, who require certain larvae host plants and habitat structures to survive. These habitat specialists are very vulnerable and have been a target of numerous nature conservations. Despite these efforts, there observation studies have shown that there is a decline of habitat specialists and the region they are observing, which used to have a diverse butterfly community, has become dominated by a few habitat generalists. Other factors include that ousting of larval host plants due to overfertilization and the ineffectiveness of nature conservation.
