Narrow-Headed Harvester Ant

A dimorphic Mediterranean ant with small minor workers and large-headed majors adapted for seed milling. Colonies build nests in dry, sunny soil with characteristic crescent-shaped refuse piles. They are abundant seed harvesters in Mediterranean ecosystems.

💡

Did You Know?

Major workers can crack seeds that are as hard as stone using their oversized mandibles powered by massive adductor muscles filling their large heads.

Wheat Stem Sawfly

A major pest of wheat and barley on the northern Great Plains of North America. Larvae bore inside stems, weakening them and causing lodging.

💡

Did You Know?

Larvae girdle the stem base before pupating, causing the stem to fall over at harvest.
