Just found so many of them hiding in my dahlias, either eating the buds or eating something else that ate the buds? I can’t be sure. They are frustrating as they keep getting in the house. It’s been very hot and dry, presumably the weather has to do with how many there are? It looks like some type of Hemiptera but I can’t narrow it down any further and we would love to know! Any info much appreciated. Thank you! Edmonton, AB. Canada
