Wasp Ascendency

Cicada-killer, whose name speaks for itself. A husky wasp that provisions its young with paralyzed cicadas, so really it’s the larva who kill the cicadas…Unknown. Possibly one of the Grass-carrying wasps of the genus Isodontia.Another Isodontia, possibly. Members of this genus use grass in the construction of their nests and prey on crickets and other Orthoptera.Humped Beewolf (Philanthus gibbosus), a bee predator.Unknown.Four-banded Stink Bug Hunter Wasp (Bicyrtes quadrifasciatus). I didn’t know there were stink bug hunter wasps.One of the Ichneumonn wasps. Says bugguide.net: “Ichneumonids are notoriously hard to identify: aside from the sheer number of species, there are numerous cases of distant relatives that appear almost identical. Any identification based solely on comparing images should be treated as suspect unless an expert has said there are no lookalikes for the species or group in question.” Note those leaf galls. Is this wasp an inquiline, a species that takes over other species’ galls for itself? By the way, the parasites themselves may be parasitized by other species.Ah, the old Four-toothed Mason Wasp (Monobia quadridens), with Carpenter Bee for scale. This big one hunts caterpillars for its young.

All the wasps on the blog. But wait! Tomorrow there will be a whole series of other wasps lately seen…

    “the parasites themselves may be parasitized by other species” astute commentary on human political systems.

    Love seeing all these wasps! Poor things have a bad rep – I pester them all the time trying to get their pictures, and they never do anything but fly away. I don’t mess with yellow jackets, though, especially later in the summer or fall.

      Some just don’t stop, very hard to get pictures of them. If they are not nectaring, they’re hunting amid the foliage.
