Geometry's Deadly Influence: How Carnivorous Pitcher Plants Capture Prey

Researchers at the University of Oxford have discovered that the shape, size, and geometry of carnivorous pitcher plants determine the type of prey they trap. By applying mathematical models to pitcher plants grown at the Botanic Garden, the team found that variations in the shape of the rim, called the peristome, have a profound effect on the plant's ability to capture prey. The study suggests that different peristome geometries are suited to capturing different types of insects, allowing pitcher plants to adapt to the various forms of prey available in their environments. Mathematical modeling provides valuable insights into the evolution and behavior of these fascinating plants, especially in remote and challenging natural habitats.

Insects Using Tools to Capture Prey: Rare Examples Found in Assassin Bugs.

Australian assassin bugs have been observed using resin from spinifex grass as a tool to catch and keep their prey. Researchers from Macquarie University found that the bugs were more successful at capturing prey when they had resin on their bodies, regardless of the type of prey. The bugs were observed scraping the resin off the spinifex leaves and meticulously applying it to their bodies, especially on their front legs. This behavior is ingrained in the insects and meets the widely-used definitions of tool use.

Australian Assassin Bugs Display Tool Use

Researchers at Macquarie University in Australia have discovered an example of tool use by an insect in Australian assassin bugs. The bugs use sticky resin from spinifex grass to help capture prey, applying it to their forelegs. The researchers found that the bugs were 26% more successful at capturing their prey when the resin was on their bodies. The resin helped to slow down the prey, making it easier to hold on to long enough for it to be stabbed.
