Turn off porch light to aid caterpillars — and safeguard backyard ecosystems
Moderate levels of artificial light at night – like the fixture illuminating your backyard – bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.
Researchers discover how bean plants fend off famished foes
A team led by scientists at the University of Washington and the University of California, San Diego has discovered that cowpeas — a type of bean plant — harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore defenses.
Study gauges insecticide effects on monarch butterflies
A newly published study sheds light on how insecticides commonly applied to crops affect monarch caterpillars. Conservation efforts to protect monarch butterfly populations depend on planting milkweed on agricultural land, but doing so may put caterpillars in close proximity to harmful insecticides.
