@arachtober@flipping.rocks  ·  activity timestamp 2 days ago

Welcome to the 19th year of Arachtober! Join us in celebrating arachnids by sharing your photos of #spiders, scorpions, and other #arachnids throughout the month. #Arachtober has spread around the web on different platforms, each with its own unique feel. Seeing the growing arachnid enthusiasm each year is fantastic! Interacting with arachnologists and other scientists has been educational and a lot of fun. For those who feel inspired to join us, if you haven’t already participated, just use the hashtag #Arachtober in your post.

For this year's banner, Ashley Bradford was inspired by my recent linocut artwork to create a digital piece in a similar style. We hope you enjoy it!

We’ve created a very basic site at Arachtober.com to help explain what this is all about, especially for those just discovering #Arachtober.

First-ever documented case of a plant mimicking ants to attract pollinators https://phys.org/news/2025-09-documented-case-mimicking-ants-pollinators.html

Olfactory floral #mimicry of injured ants mediates the attraction of kleptoparasitic fly #pollinators https://www.sciencedirect.com/science/article/pii/S0960982225011261

"Vincetoxicum nakaianum (a #dogbane species native to #Japan described only a year ago) mimics the smell of #ants attacked by #spiders. This scent attracts #flies that feed on these injured #insects and pollinate the #flowers in the process."

First-ever documented case of a plant mimicking ants to attract pollinators

Ko Mochizuki of the University of Tokyo has discovered that Vincetoxicum nakaianum (a dogbane species native to Japan described for the first time by Mochizuki and his collaborators only a year ago) mimics the smell of ants attacked by spiders. This scent attracts flies that feed on these injured insects and pollinate the flowers in the process. This is the first case of a plant mimicking the odor of ants, revealing that the scope of floral mimicry is more diverse than previously imagined. The findings are published in the journal Current Biology.
