Very interesting and, I guess, rarely observed species, Claude. I hardly managed to find some scarce information about it. Great find! Posted 4 years ago

  Thanks for the species creation, Jivko, looks like we were going at it at the exact same time :)
  On point, a little while ago I was hoping we could get to 1,500 species this year. Things somehow have accelerated since then and now we're only 10 away! Posted 4 years ago

    You mean 1,500 species of beetles? Yes really. I hadn't paid attention to that, but it's really a remarkable achievement! Posted 4 years ago

      I think it really is! And after that we'll do the other 299,000 in no time. Posted 4 years ago

        Wow, no doubt!
        Ferdy, do you have an analysis what is the growth of the added new species every year since the creation of the site? Posted 4 years ago

        I can maybe create that report once I have more time, but for now maybe this answers the question: new species added per week is usually between 50-100, and this number is surprisingly stable, has been like this for at least a few years. I think 60 would be a good conservative average, so that means at least 3,000 per year. Posted 4 years ago
