Helmeted Squash Bug

A North American coreid with an expanded helmet-like pronotum. It feeds on various plants but is not as destructive as the common squash bug.

💡

Did You Know?

Its expanded pronotal 'helmet' makes it look significantly larger from the front, potentially deterring predators.

Cylindrical Tachinid

A slender, wasp-like parasitic fly with a narrow cylindrical abdomen. Parasitizes shieldbugs by laying eggs directly onto the host. Found in warm, flower-rich habitats.

💡

Did You Know?
