I look forward to the Eastern edition to help me ID ‘hoppers in Iowa! ### 1/5 — disappointed *2016-05-05, version 1.0.2* I'm familiar with the fact sheets used in this app and they are excellent. The only problem is you can't get to them directly. You have to go through a laborious taxonomic key. Too bad you cannot just read facts about and see photographs of species without the hassle. Really disappointed. ## Frequently asked questions about Grasshoppers of the Western US ### What grasshopper species can Grasshoppers of the Western US identify?
