Collective Prey Capture By Juvenile Venus Flytraps (Dionaea Muscipula), Steven Rosen
Collective Prey Capture By Juvenile Venus Flytraps (Dionaea Muscipula), Steven Rosen
Honors Theses
The Venus flytrap (Dionaea muscipula), first described by Charles Darwin, is a unique carnivorous plant which acquires prey using leaf blades modified into snap-traps. A recent study showed that prey capture by flytraps was not selective. With this study we examined prey capture rates further by analyzing D. muscipula traps less than 1 em in length to determine if juvenile flytraps differ from adults. Similar to the earlier findings, trap size appeared to play no role in prey capture success. This was likely due to the fact that 88% of all prey items recovered were smaller than the smallest collected …

Prey Capture In Response To Removing Cilia From Venus Flytraps, Emily Marchini
Honors Theses
Carnivorous plants are able to attract, trap, and digest insects. Different types of traps target different prey. There are sticky traps, pitfall traps, and active steel traps (Gibson, 1991). Although this may seem to be a rare modification it appears that there are six origins of carnivorous plants in different groups of angiosperms (Albert et al., 1992). These results indicate that not only were there multiple origins of carnivorous plants, there were also multiple origins of the same trapping mechanism; for example, the flypaper trap has five origins and the pitcher trap has three (Albert et al., 1992). Multiple origins …
