Biodiversity, plants & animals Easy

The organisms "Cicada, Froghopper and Pond skater" are:

Answer & explanation

Answer: (c) Insects

All three are insects, and all three belong to Hemiptera, the true bugs. The cicada is the loud 'singing' insect of trees, the froghopper (spittlebug) is a small jumping insect whose young hide in blobs of froth on plants, and the pond skater (water strider) runs across the surface film of still water.

  • ✓ (c) Cicadas and froghoppers (spittlebugs) are grouped in the Auchenorrhyncha, and water striders (pond skaters) in the Heteroptera; both groups are true bugs (order Hemiptera), and true bugs are insects with six legs and a body in three parts.
  • ✗ (b) The pond skater lives on water but never under it: water-repellent hairs on its legs let it stand on the surface, and it breathes air like other insects.
  • ✗ (d) 'Froghopper' is only a name for its frog-like leap; it is a small bug, not a reptile or an amphibian.

Remember · Cicada (Cicadidae), froghopper or spittlebug (Cercopidae) and pond skater or water strider (Gerridae) are all insects of the bug group Hemiptera.
