Pear Fruit Sawfly

A small, dark sawfly that is a pest of pear orchards. Larvae bore into developing pear fruitlets, causing premature fruit drop.

💡

Did You Know?

Infested young pears often show a distinctive entry hole with wet frass, and a single larva may damage two to three fruits before completing development.

Amazon Ant

A slave-making ant that raids colonies of Formica ants to steal pupae, which then emerge as workers in the Polyergus colony. The sickle-shaped mandibles of Polyergus workers are adapted for combat but useless for foraging or nest maintenance. They depend entirely on their captive workers for food and brood care.

💡

Did You Know?

Without their enslaved workers, an entire colony would starve because their sickle-shaped jaws make them incapable of feeding themselves.
