Importance of Insects

2) What were the most feeding visits observed in a single hour?

• Hairy Woodpecker at 3PM

• Hairy Woodpecker at 9AM

• Sapsucker at 9PM

• Sapsucker at 11AM

3) Roughly how many total feedings did the sapsucker adults provide between 5 AM and noon?

• 8-10

• 35-45

• 65-75

• 20-30

4b) How many caterpillars per day would each baby bird eat if there are 5 chicks in the nest?

• ~18

• ~46

• ~228

• ~132

5) Which option best describes how native v. novel plants impact caterpillar populations?

• Native plants are better by all measures

• Novel plants are better by all measures

• Novel plants support fewer species but more caterpillars

• Native plants support fewer total caterpillars but more species

6) What impact could plant type have on local bird populations?

• Choosing native plants would provide more food for birds

• Choosing novel plants would provide more food for birds

• Neither native nor novel plants have a major impact on bird populations

9) Which option best describes whether a maple or pine might attract more bird species?

• Maples host more caterpillars, which are bird food

• Pines host more caterpillars, which are bird food

• Maples host about 13% of birds, which is more than pines

• Pines host about 13% of birds, which is more than maples

10) Which description best ties all the concepts together from this handout?

• Human plant choice in developed areas has a major impact on insect & animal populations

• Insect & animal populations tend to not be affected by human plant choice

• Choosing novel species can introduce new insects to an area, which will bring new bird species

• Native plants, while once thought to be important, do not help support local ecosystems
