The result was a master template that retained those useful nanoscale features and can be used to make solar cells."

I believe you meant to refer to PETI?

Blowflies are very much out of the "nature red in tooth and claw" school, only nastier. They need substantial amounts of protein to successfully lay their eggs and develop their horrid maggots. The nicest ones deal with this by hunting down and infesting carrion. The less pleasant ones don't like to wait. In tropical areas, this so-called "fly-strike"(infestation of wounds/sores/damp areas by live maggots feeding on host tissue) is a nontrivial health threat to both humans and animals. I leave the google-images-ing of "flystrike" "Myiasis" and "screwworm" to the reader; but it isn't pretty.
PETA's leadership are genuinely odd ducks; but their rank and file are mostly tactless idealists who are all warm and fuzzy about animals(you'll notice, for instance, that the idea that pets=slavery doesn't feature strongly in fundraising/membership drive literature). Even if they aren't idealistic/fuzzy enough to care about poor children in dusty countries who have maggots in their eye sockets, the fact that these insects will infest, and kill slowly and painfully, all sorts of cute fuzzy animals should do the trick...

I've often wondered why we think that every creature was made by a supreme being with a specific purpose in mind.
