leaf-footed bug nymph

6094    Please tell me what this is.   I live in Quinte West, Ontario and this bug was on my screen door around dinner time. I live close to a creek and have many spruce and cedar trees around. The she’ll on its back almost looks prehistoric with spikes on it.  Hope to hear from you. Dana 

This is a nymph of a leaf-footed bug (Hemiptera/Heteroptera; Coreidae); likely Acanthocephala terminalis – see https://tinyurl.com/yck2aytl for an image. This does not appear to be a serious pest species. Ed Saugstad, retired entomologist; Sinks Grove, WV.
