BPA is a building block of clear hard plastics, dental sealants and the resins lining food cans. Studies have shown that throughout the industrial world, nearly everyone regularly encounters the compound, albeit at trace concentrations.
How do those offspring come about if the females don’t have genitals? That’s where this female insect’s life gets even more miserable: To get those cannibalistic kids, she has to


That’s small consolation, says Laura Vandenberg of Tufts University in Medford, Mass.: In the new BPA study, “the most effective dose was very close to — if not completely overlapping — what’s been reported in humans,” she says.

Bisphenol A toys with the female heart, a new study finds. And under the right conditions, its authors worry, this near-ubiquitous pollutant might even prove deadly.
The females of Stylops ovinae, a parasitic insect species that lives in mining bees, have pretty dull lives. While the males, tiny winged insects, get to flit about — for a few hours, at least, before they die — the females are literally stuck at home, wedged inside a mining bee for their entire lives with only a bit of their cephalothorax (neck) exposed. And worse, once a female’s offspring hatch, they will eat her alive. Oh, and they’ve got no wings, legs, antennae, eyes, mouthparts or genitalia.
