<\/a>A moth larva called a looper investigates sticky asphodel capsules and will later eat the seeds. (Mary F. Willson \/ For the Juneau Empire)<\/p><\/div>\n\t\t\t\t
However, as noted above, our little study did not find the marker isotope in roots or seeds. So we can hope that further research will resolve this issue.<\/p>\n\t\t\t\t
Nevertheless, the new research clearly shows that, assuming our species is like the other, we have another local member of the insectivorous-plant clan, along with two species of sundew, bladderwort, and butterwort. I’m sure that more will be discovered, if we would just look!<\/p>\n\t\t\t\t
Back in the 1980s, one of my PhD students showed that labelled nitrogen was taken up in sticky traps on the inflorescences of Penstemon digitalis and Cirsium discolor. In P. digitalis, sticky hairs occur on the flower itself and its stem; in C. discolor, the traps are on the outer involucral bracts just below the flowering head. The pollinators of penstemon (bees) are too big to get stuck on the traps, and the assorted pollinators of Cirsium approach the flowers from above, and so do not encounter the traps. No defensive function of those traps was found. Instead, the sticky traps had digestive enzymes and provided extra nitrogen and phosphorus to the plants, and this resulted in increased numbers of seeds by both species. Unlike most species that are known to be insectivorous, these two do not inhabit very nutrient-poor habitats such as bogs.<\/p>\n\t\t\t\t
