Vegetarian Carnivores. The first video in our new series "Siggi's CP Info" Is it possible to grow your carnivorous plants with vegetarian diet? Our first film from the new “Siggi’s CP Info” series provides the answer. Carnivorous plants predominantly capture and digest arthropods like insects, spiders or little crustaceans. Some of the largest tropical pitcher plants are even known to eat real meat, mostly small vertebrates like mice or reptiles. But what happens if you feed vegetarian food to the carnivores? Even Charles Darwin pointed out that in times of high pollen abundance the

Never fear! You do not need a chemistry book to understand this film. Showing a bunch of beautiful sundew species and hybrids, we explain really briefly and clear why particular chemical ingredients of the sundews are not only interesting as cough medicine for homeopathy, but also as traits for taxonomy, in a manner as comprehensible for laypersons as possible. The featured chemical analysis (TLC) is helpful for the description of novel species and gains an additional dimension by the fact that most true species produce only one naphthoquinone or none, while hybrids show the chemistr

How to film sundew snap-tentacles. When filming sundew snap-tentacles, some simple measures can be helpful to prepare the recording correctly and to avoid disturbing shaking by unnecessary poking of the tentacle heads. That needs some understanding on their different response times and motion patterns. Since many years, we experimented with catapulting sundews and summarized our experiences now in this brief movie description, providing hints how to proceed with moderate and rapid catapult-flypaper traps. The idea for this film came up after some requests on Facebook how to film such tent

Amazing results: Pygmy sundews capture minute prey like springtails with rapid catapult action. Our experiments for this film (English subtitles) show that Drosera glanduligera is not longer the only sundew with a catapult-flypaper trapping mechanism. Also the snap-tentacles of several pygmy Drosera act with the speed of a closing Venus flytrap and fling walking prey from the periphery of the plant onto its sticky leaf. Therefore they turn out to be actually comparable with the amazing Drosera glanduligera, however, their catapults are multifunctional and possess a mechanism to avoid unessenti
