European hornet, Vespa crabro

6309 These wasp have a nest somewhere in the side of my house. They are the largest wasp I have seen and are intimidating. I just started noticing them (August 20). They are attracted to light and always get trapped in my garage. What type of insect are they and what precautions should I take as a hole owner. From Kingston, Ontario

Number 6309 This looks like a European hornet, Vespa crabro (Hymenoptera: Vespidae). These tend to be less aggressive than their smaller cousins, yellow jackets and bald-faced hornets. However, they will sting in response to being stepped on or grabbed and also are defensive of their nests and can be aggressive around food sources. They primarily are carnivorous and hunt large insects, but also will feed on fallen fruit and other sources of sugary food. Click here for more detailed information.

Insect Eggs or not?

6249 What type of bug/insect are these eggs? They jump all around at times, I can’t find anything online about them. From Winnepeg, Mb

Number 6249 – I’m not at all sure what these might be. The only insect-related object I know of that resembles these are the pupae of ichneumon wasps in the subfamily Campopleginae, but those are more elongate than the objects seen in your image; Click here for an example. Also, there some plant seeds that when infested with an insect larva will ‘jump’ (such as so-called Mexican jumping beans) as well as some plant galls, but none of them look anything like your images
