North American walnut sphinx moth caterpillars (Amorpha juglandis) look like easy meals for birds, but they have a trick up their sleeves — they produce whistles that sound like bird alarm calls, scaring potential predators away. At first, scientists suspected birds were simply startled by the loud noise. But a new study suggests a more sophisticated mechanism: the caterpillar’s whistle appears to mimic a bird alarm call, sending avian predators scrambling for cover. When pecked by a bird, the caterpillars whistle by compressing their bodies like an accordion and forcing air out through specialized holes in their sides. The whistles are impressively loud — they have been measured at over BO dB from 5 cm away from the caterpillar — considering they are made by a two-inch long insect.
  • a)
    North American walnut sphinx moth caterpillars will whistle periodically to ward off predator birds – they have a specialized vocal tract that helps them whistle.
  • b)
    North American walnut sphinx moth caterpillars can whistle very loudly; the loudness of their whistles is shocking as they are very small insects.
  • c)
    The North American walnut sphinx moth caterpillars, in a case of acoustic deception, produce whistles that mimic bird alarm calls to defend them selves.
  • d)
    North American. walnut sphinx moth caterpillars, in. a case of deception and camouflage, produce whistles that mimic bird alarm calls to defend themselves.
Correct answer is option 'C'. Can you explain this answer?

According to the paragraph the North American walnut sphinx moth caterpillars produce whistles which are extremely loud considering their size. These whistles appear to mimic bird(predator) alarm calls which scares them to look for cover. Thus, these sounds act as acoustic deception and help the insect to defend themselves against predators.
Option A mentions about vocal tracts which is out of scope. Hence, it can be eliminated.
Option B though correct, fails to mention the use of sound to defend against the preators. Hence, it can be eliminated.
Option C captures all the main points and hence is right choice.
Option D mentions ‘camouflage’ which is also out of context. Hence, it can be eliminated.
Hence, option C is the right answer.

Explanation:


North American walnut sphinx moth caterpillars have a unique defense mechanism where they produce whistles that mimic bird alarm calls. This deceptive tactic helps them ward off predator birds effectively.

Key Points:


- The caterpillars produce whistles that sound like bird alarm calls.
- The whistles are loud, measuring over 80 dB from a short distance.
- This mimicry of bird alarm calls startles avian predators, causing them to retreat.
- The mechanism involves compressing their bodies to force air out through specialized holes, creating the whistling sound.

Therefore, the author's position is that North American walnut sphinx moth caterpillars employ acoustic deception by mimicking bird alarm calls to defend themselves against predators.

Answer the following question based on the information given below.Animals can habituate to environmental disturbances. Whats more, they can get very good at telling the difference between stimuli that are relevant to them, and those that arent. Tree frogs can tell the difference between vibration caused by a predator and vibration caused by rain, even though these cues are extremely similar. Similarly, caterpillars living on leaves can tell the difference between vibrations caused by other caterpillars, predators, wind and rain.Spiders build webs on human-built structures such as pipelines, fences, road signs and wire rods, all of which are made out of materials not present in their evolutionary history. This means that they will absorb vibrations from the environment differently to a more natural place a spider might build its web, for example a plant. If these human-built objects are anywhere near humans (which they are likely to b e) they are also probably affected by human noise. For example, a spider that has built a web near a road will be subject to the vibration caused by cars driving by. This matters particularly to spiders because they use vibration so much in guiding their behaviour. Indeed, you can even imagine the web to be an extension of the spider itself, such that the vibrations on the very outside of the web travel down to the spider situated in the centre and tell it whether its being touched by prey, a mate, wind or rain.Q.Read the sentences and choose the option that best arranges them in a logical order.A. Its author, Benjamin Lee Whorf let loose an alluring idea about languages power over the mind, and his stirring prose seduced a whole generation into believing that our mother tongue restricts what we are able to think.B. Eventually, Whorfs theory crash-landed on hard facts and solid common sense, when it transpired that there had never actually been any evidence to support his fantastic claims.C. In 1940, a popular science magazine published a short article that set in motion one of the trendiest intellectual fads of the 20th century.D. For decades, Whorfs theory dazzled both academics and the general public alike. In his shadow, others made a whole range of imaginative claims about the supposed power of language, from the assertion that Native American languages instil in their speakers an intuitive understanding of Einsteins concept of time as a fourth dimension to the theory that the nature of the Jewish religion was determined by the tense system of ancient Hebrew.E. In particular, Whorf announced, Native American languages impose on their speakers a picture of reality that is totally different from ours, so their speakers would simply not be able to understand some of our most basic concepts, like the flow of time or the distinction between objects (like stone) and actions (like fall).
