Booklice feed on 1. molds and fungi 2. cereals and pollen.

• A. 1 is true, 2 is false
• B. 1 is false, 2 is true
• C. both are true
• D. both are false

Answer: (C)

Booklice are tiny, moisture-loving insects that eat what’s available in their humid environments. Their main diet is molds and fungi growing on surfaces like old books, wallpaper, and damp organic matter. They’re opportunistic feeders, so when cereals or other starch-rich foods are present and may be moldy or dusty, booklice will feed on those as well. Pollen can also appear in their habitat, especially in plant debris or stored plant materials, and they’ll take advantage of it when available. Because of this flexible feeding, both statements are true: they eat molds and fungi, and they can feed on cereals and pollen when those foods are available.
