Insect Facts and Behavior

Grasshoppers can swim temporarily using a leg-kicking motion that allows them to stay afloat for short periods, though they're not aquatic insects. This survival mechanism helps them escape danger, making option A correct.

Female mosquitoes bite because they require proteins from blood to develop their eggs. Male mosquitoes feed exclusively on plant nectar and do not bite, making option A correct.

Insects rely on a trade-off between sensory organs - those with well-developed compound eyes typically have shorter antennae, while those with poor vision develop longer antennae for enhanced tactile and chemical sensing, making option A correct.

Both adult fireflies and their larvae (called glowworms) can produce light through bioluminescence. The claim that only adults emit light is incorrect because larvae also use light signals to attract prey and deter predators.

Spittlebug nymphs create protective foam shelters that resemble bubbles or spittle. This foam, produced by mixing plant sap with air, shields them from predators and prevents drying out.

Ants use their antennae (commonly called 'feelers') as their primary sensory organs for smell and touch. These appendages contain chemical receptors that detect pheromones and other scents.

Ladybugs can secrete a yellowish fluid from their joints when threatened, but this serves as a warning signal (aposematic coloration), not camouflage. The bright color is meant to be conspicuous to warn predators, not hard to notice.

Crickets are nocturnal and hide during the day in vegetation or crevices, making them difficult to spot. Their loud chirping sounds make them much easier to hear than to see.
