How far can the average charge of a butterfly move pollen grains?

• At least six millimeters

• At least ten millimeters

• At least three millimeters

• At least eight millimeters

What factor might cause variation in the electrostatic charge across different species of lepidopterans?

• Differences in body surface area

• Differences in wing color

• Differences in diet

What is the relationship between the polarity of a charge and its benefits in a species' environment?

• Higher positive charge helps detect flowers' electric fields

• Negative charge helps in photosynthesis

• Positive charge helps in camouflage

• Negative charge helps in pollination

Why might lepidopterans from the tropics have a negative charge?

• To cloak them from predators

• To attract more mates

• To enhance their color

• To increase their size

What is the significance of detecting flowers' electric fields for insects?

• It helps them find nectar

• It helps them avoid predators

• It helps them migrate

• It helps them reproduce
