Which of the following is known to not typically prey on aphids?

Squash bugs are known to be herbivores that typically feed on the sap of plants, particularly those in the squash family, rather than preying on aphids. This makes them less likely to be involved in controlling aphid populations. In contrast, ladybugs, parasitic wasps, and hoverflies are all known beneficial insects that actively hunt and feed on aphids. Ladybugs, for instance, are voracious predators of aphids in their larval and adult stages. Parasitic wasps lay their eggs inside or on aphids, leading to the eventual death of the aphids. Hoverflies, particularly in their larval stage, also consume aphids. Understanding the feeding habits and ecological roles of these insects is crucial for managing pest populations in agricultural settings and promoting beneficial species that aid in pest control.
