  Over the next couple of episodes we are going to be dipping into a different group of life than we usually do, the plants. Mike has been getting back into carnivorous plant rearing and wants to share all he knows about the world of plants that eat bugs. How the tables can turn!     Darwin's drawings of the leaves and tentacles of a sundew (Drosera rotundifolia), Figures 1, 4, and 5 from "Insectivorous Plants" (1897), in the public domain.  Aphids and other small insects caught in the sticky trichomes of Nicotiana insecticida, a newly described species of tobacco from Australia. Photograph by Maarten Christenhusz, Figure 1 in Chase & Lambkin (2021).    Phylogeny angiosperm plants with carnivorous taxa indicated by numbered circles. Illustration by Andreas Fleischmann, in Fleischmann et al. (2017) "Evolution of carnivory in angiosperms" in Ellison & Adamec (eds) "Carnivorous Plants: Physiology, ecology, and evolution". A wetland in Loyalsock State Forest, Lycoming County, Pennsylvania that is home to temperate sundews.

Nepenthes ampularia are a species that have adapted away from carnivory and instead capture leaves that fall from the canopy. Photograph by CIFOR via Flickr, used under a CC BY-NC-ND 2.0 license. A spoon-leaved sundew, Drosera spatulata. This species has a circumboreal distribution with an isolated population also found in the highlands of Borneo.

Venus fly traps being sold commercially. Photograph by Mike Mozart via Flickr, used under a CC BY 2.0 license. A waterwheel plant (Aldrovanda vesiculosa), which have snap traps and are closely related to Venus fly traps. This species is at risk in their native range but have been introduced into North America, where they may be invasive. This specimen was photographed at Fort AP Hill in New York, USA. Photograph by the U.S. Government, in the public domain. Individual Aldrovanda nodes showing the whorl of leaves and snap traps. Photograph by David Short via Flickr, used under a CC BY 2.0 license. A young dewy pine (Drosophyllum lusitanicum) grown in culture. While this sticky-leaved plant may look like a sundew, they are only distantly related to one another.
