Rapid Prey Slinging Sundews It always looks sensational when the rapid catapults of some sundews fling their prey into the sticky tentacles of the trapping leaf in a matter of seconds or even milliseconds. The largest of the catapult-flypaper traps known to date, Drosera glanduligera, is even faster than the famous Venus flytrap. In the past, who would have thought a sundew could do that? The exciting research into these fast trapping movements in the genus Drosera only began in the 1980s with the still rather sedate Drosera burmannii / D. sessilifolia. We show with impressive recordings how research into the fast catapults progressed. Even today there are still surprises. In this film we show all known rapid catapult-flypaper traps and present video evidence of the tentacle movement of Drosera australis, a further rapid pygmy Drosera.

Monitoring Venus Flytraps in Florida: Amazing 1-year timelapse About 1500 km south of their native habitats in the Carolinas, Venus flytraps (Dionaea muscipula), propagated from seeds, find a comparable environment in open long leaf pine forest on the property of Bill Scholl in northern Florida. Originally, they relied on occasional wildfires that remove not only dry undergrowth but also the wiregrass that often grows over them. Presently, on Bill’s property, they benefit from controlled burns done by Bill and his burn team to manage the habitat. ften only the parts of the Venus flytraps near the surface are killed by the fire so they quickly resprout in areas cleared of overgrowth, although, where wiregrass is abundant it rapidly grows over the flytraps. In the summer, tropical storms and hurricanes are common with heavy rains that temporally inundate the Venus flytraps. A controlled burn was done on the forest surrounding the Venus flytraps in this timelapse in April, the effects of which can easily be seen in this amazing timelapse over the complete year of 2022. We (Irmgard and myself) edited and produced this film in collaboration with Dr. Stephen Williams (USA), who assembled the timelapse sequences from daily photos taken by a stationary wildlife camera, and Bill Scholl, who did the video monitoring on his property.

My typical flytraps (Dionaea muscipula) grow in same pot together in the same location, yet some traps are deep red, larger and they lie close to the ground. Other traps on another typical vft are lime green (no red whatsoever) and grow to various sizes and vertically straight up into the air. What could explain these stark differences considering same pot, same typical Dionaea muscipula species and same location and water?

Dionaea Traps Selectively Allow Small Animals to Escape. Our prey capture experiments show that Venus flytraps (Dionaea muscipula) selectively allow small animals to escape by a system of interlocking features that complement each other very efficiently. We documented ants of the species Lasius neglectus (length 3.5 mm) running continuously through open traps of Dionaea, established since more than 20 years outdoors in our garden. To achieve statistical relevant results, we did not only count, identify and measure captured prey. Other than in former publications, we counted also the escaped ants (15,000 after 28 days) to be able to calculate the risk for small ants visiting active traps. Surprisingly, their risk to get captured is 2.5 times lower (0.04%) than the risk of mortality by medical malpractice for a human in a German hospital (0.1%). None of the four single features of the interlocking "escape system" described here would alone be able to provide such an efficient sorting out of small animals. This film is based on the same named publication in Carnivorous Plant Newsletter (December CPN, Vol. 48/4 - On the release of this film in September 2019 in press): Dionaea Traps Selectively Allow Small Animals to Escape by Siegfried R. H. Hartmeyer, Irmgard Hartmeyer and Emeritus Prof. Stephen E. Williams.

Our movie "Prey Capture by Dionaea muscipula" is based on the same named CPN article (June 2017) by Emeritus Professor Stephen E. Williams and Siggi Hartmeyer. What captures Dionaea in cultivation compared with the natural habitat in North Carolina? How does it attract prey? Is UV-reflection and/or fluorescence used for attraction? Did it even develop a strategy to capture preferred larger prey animals than small ones? Well, it looks like that, but how does it work? Simply enjoy our documentary and find the answers. A HD-movie in the German language with English subtitles. Kind regards, Siggi & Irmgard.

Hi I have sown some D.muscipula 'Red Giant' seeds at the end of November and they are not doing much since then to the present day. From what I have read up on venus fly traps is that they do not take long to germinate and are the most easy cp to grow from seed. The media I used is a 1:1 moss peat, grit sand mix with live sphagnum on top and the seeds were sown onto the moss. They are pushed ever so slightly into the moss but enough that they were not entirely covered and have more contact with the moist moss. The seed tray that they are in are sat into a water tray and covered by the seed tray cover. Which is slightly too wide for the tray and leaves a bit of a gap that acts as a vent. At first the seeds were on a west facing window cill that does not get much light this time of the year and a heat mat was placed under the water tray after a couple of weeks of sowing to provide a bit of heat. They were then left there for another couple of weeks and had noticed that nothing was happening. After reading some care sheets which said that light is a key factor for their germination, I then moved the tray and the heat mat to a south facing window where there is more light. They were placed on the cill around the 14th - 16th of last month and are there to the present day. But there is more activity from the moss (which is not very much) than the seeds and there is no sign of dampening off. I am wondering whether I have missed something or I am being a bit impatient and have to give them more time. Unfortunately I am unable to post any pictures up as tapatalk does not seem to work properly on my phone. But I will be grateful for any tips and advice that is given. Mike

During my college years, one of my best friends, Dr. William Ratcliff aka Will, grew out some seeds that he purchased from Orton's plantation in the Carolinas (I think he bought these around 2002 or 2003). We suspect these were wild seeds collected from private property, as they were only sold in lots of 1000 or more. Will graduated in 2005 and had to move to Minnesota for his graduate studies, so he graciously gave me all of his plants. At the time, I wasn't into venus fly traps so much, so the pot was placed among the Sarracenia. They were jammed into a 4" pot and neglected for more than half a decade! No repotting, no TLC, nuthin! Out of 50+ seedlings, only a few survived and it was clearly the strongest and tougest of the bunch. This goes to show this clone has great breeding potential since it tolerated such severe neglect. When I finally got interested in VFT's again, the pot was overgrown with weeds and smothered with dead Sarracenia leaves (it was late winter and time to repot!) In fact, the plastic pot crumbled into pieces when I picked it up since it was so weathered from the sun! Dionaea "Orton's Red Side" as I'll tentatively call it was repotted and "grown for Jesus." After the first year of recovery, the 3 or so main plants produced huge traps! This clone can turn reddish on the inside of the trap (like most venus fly traps), but what makes this individual stand out from the crowd is its ability to produce red pigments on the outside of the trap while still having a solid green petiole and somewhat green interior. Environmental conditions play a huge role in this phenotype, but it also seems to be genetically based. The petioles very long petioles and can produce decently large traps. Over time, as the "bulb" grows large, it'll split into 2 or 4 plants, and the back of the bulb will form a few tiny plantlets. You know you have a vigorous clone when it constantly divides on its own (reminds me of B52). The fact that it does very well outdoors here in Northern California says a lot as well:it seems only the most vigorous VFT clones do well for us here. Some photos, taken 8/7/15. What's ridiculous is how I've had this plant for years and didn't fully notice the unique characteristics until now: The exterior of the trap. Notice there are some "normal" clones from the same seed batch mixed in this pot: The plants "shrunk" this year because I let them flower. Some of the stalks were as thick as baby asparagus: These plants were enormous last year, I'll pinch off the flowers next year and see if I can get them giant. Here's a picture of after the flowers finished taxing the plants:

Having started my Carnivorous Plant journey (some ten years ago) by growing a handful of plants outdoors (due to lack of a greenhouse at the time), I've now returned to displaying a few plants outside; in a couple of newly set up bogs... A Darlingtonia haven on the left, and a mixed species bog on the right: The Darlingtonia are in a very watery/soupy mix of pure Sphagnum & rain water, and has a solar-powered airstone at the bottom to create a bit of oxygenation - in full sun the water really bubbles away! The Belfast sink bog, consists of S. × 'Maxima', S. purpurea venosa, S. × harperi, S. oreophila 'Purple Throat', Dionaea muscipula (seed grown myself), Dionaea muscipula 'Akai Ryu', Drosera capensis 'Alba', Pinguicula grandiflora & Utricularia dichotoma. It is a sphagnum, peat & sand mix with a blanket of sphagnum on the surface. It will be interesting to see these progress over the year(s), especially the Belfast sink, which should fill in nicely with D. capensis seedlings, P. grandiflora gemmae and the spreading U. dichotoma (providing it doesn't completely die off during the winter!)

Hi. Like many of you CP growers out there, i enjoy observing my plants and seeing them feed naturally on flies and other insects, non more so than my Dionaea. I have noticed that flies feeding on the Dionaea Muscipula 'nectar' seem to become intoxicated slowing them down dramatically. Now i know American pitcher plants nectar is proven to have this kind of effect but this observation i noticed before i owned any pitcher plants. Also my pitcher plants are kept in a different green house this year yet i still regularly observe this behavior in the flies around my Dionaea. I've yet to see any written confirmation of this characteristic though i admit i don't own much litterateur on the subject so have just browsed the internet. I was just curious if any of my fellow CP growers out there have observed this or have seen any written confirmation? Happy Growing. 0rmus.

Here's some photos of very well grown venus fly traps at California Carnivores. There's so many different varieties, and unfortunately, I'm not up to date on my flytrap ID, but in any case, it's really neat to see all the different clones out there. Fortunately, Some of the pictures have tags that are readable. 10 years ago, there was Akai Ryu and maybe a handful of cultivars. Today, there are countless clones: Burbank's Best Pretty sure this is B52: And the Grand Finale-these are ridiculously beautiful:

Hello everyone! I don't know if any of you remember me but I started posting on this and similar websites (e.g. terraforums) at the young age of 12, almost 10 years ago! I'm now 20 years old and studying Plant Science at the University of Manchester. Still having a keen interest in carnivorous plants, I have fortunately managed to convince my supervisor to allow me to study nutrient uptake in Dionaea muscipula for my final year dissertation. To put it simply, I want to find out exactly why they experience stress and die in high nutrient soils - what is it that makes them sensitive? My theory is that it's down to either having highly efficient nutrient uptake channels in the roots, which would have evolved to make the most of what little nutrient is available in peat soil. As we all know, VFTs can still be grown (albeit more slowly) without being fed - they therefore must be getting nutrient from the soil, the traps only supplementing their diet. I also think perhaps they have lost the mechanism by which to stop nutrient uptake in their roots when it reaches high levels. Due to this, the plant cannot control uptake of nutrients and so nutrient content quickly reaches toxic levels, stressing and killing the plant. My first idea is that I will test different levels of nutrients (such as potassium, zinc, etc) in the growing medium and find out if there is a particular mineral that VFTs are sensitive to. Although this is more scientific than horticultural I thought some of you may be interested in helping me out with this. I have only just begun to plan my experiment but wanted to hear any feedback of your own experiences with VFTs relating to this, and any opinions or suggestions you may have. For example, what in your opinion are the main signs of stress due to high nutrient in the medium? How long would it typically take a plant to die? Has anyone every tried fertilising VFTs? Etc etc.. all feedback welcome! I may also start a poll to help collaborate data from everyone's experiences (if that's okay with you mods?). I'd also like to know whether anyone can advise on where I can purchase wholesale VFTs cheaply - preferably propagated so they are all clones and of known, same age? If any of you run a commercial website I would be so appreciative if you could send me a message to let me know who your supplier is - I need to keep costs down as I have a very limited budget as an undergrad and so need to remove the middle man so to speak. It's purely for scientific research so there's no risk of commercial competition or what not! I look forward to hearing from everyone! Best, Danny
