Effort clarifies major branch of insect tree of life

CHAMPAIGN, Ill. — The insects known as Hemiptera are not a particularly glamorous bunch. This group includes stink bugs, bed bugs, litter bugs, scale insects and aphids. Their closest relatives are thrips, bark lice and parasitic lice. But with a massive number of species, two-thirds of which are still unknown to science, these insects together make up one of the twiggiest branches on the tree of life.

A new study published in the Proceedings of the National Academy of Sciences collected a vast amount of molecular data on these insects and used the information to help tease out their family relationships and evolutionary history. The findings – and the data, which are now publicly available – will aid future research into some of the most abundant and economically important insects on the planet, the researchers said.
