The edible insects market is new and there's not a single place where you can find all the informations to understand it, its recent past or the development forecasts for the future also in terms of billions of dollars (except in a couple of very expensive "studies").
Picking up informations about the edible insects companies and market outside Europe is even more difficult (maybe not for the data coming from the USA).
A useful way to get a picture of the situation is reading the interviews made by the Entomofago team that interviewed a lot of entopreneurs, experts and researchers all over the world… so have a look to their site and enjoy the articles!
