Adult blue morphos rarely visit flowers — they prefer rotting fruit, fermenting sap, and the moisture from fungi.

A botfly larva develops under the skin for six to eight weeks before emerging — and adult bots themselves live only a week or two.

Goliath beetle larvae are carnivorous — they eat decomposing meat and other invertebrates, unusual for a scarab beetle larva.

Roasted goliath birdeater is a traditional Venezuelan and Guyanese delicacy — flavor is reportedly close to shrimp.

Larvae eat freshly-burned wood that other insects can't process — they have a competitive monopoly on charred timber.
