Furniture Booklouse

A minute pale booklouse often found in new homes and recently plastered walls. It feeds on microscopic mold in damp indoor environments.

💡

Did You Know?

Outbreaks in new buildings disappear once the structure dries out and mold can no longer grow on fresh plaster.

Stalk-Eyed Fly

Males have eyes on the tips of long rigid stalks that can span wider than their body length. Females prefer males with wider eye spans, driving extreme sexual selection.
