With the ID-a-thon underway, I was wondering if people wanted to share their resources for making identifications. I know that iNat staff will be sharing resources throughout the month, but I’d love to see what other people have created or found that is helpful for their groups of organisms. Here …

I made this guide for identifying US and Canadian ticktrefoils using parts commonly photographed by iNatters (a combo of distinguishing the two similar genera and identifying the species in the smaller genus): Identifying Hylodesmum and distinguishing it from Desmodium (still working on an accompan…

I made an introductory guide to IDing caterpillars in the eastern US and Canada last year! The example species used are generally extremely common in the Caterpillars of Eastern North America project , but I was mainly trying to help people get to family/subfamily, so it may still be somewhat helpful…

kinda niche but here’s a project I have created for mantis oothecae https://www.inaturalist.org/projects/mantis-oothecae-of-india and here’s the one for overall mantodea diversity in India https://www.inaturalist.org/projects/mantidsindia

Similar to Gallformers, there is an European equivalent called “Plant Parasites of Europe” that covers leafminers, galls, and fungi on plants :). I use it pretty often in Germany these days and you can also look up by host plant, like Gallformers. It’s available in English :) https://bladmineerders…
