Idionyx travancorensis is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Idionyx travancorensis rather than just read about it. In short: Idionyx travancorensis is a species of dragonfly in the family Idionychidae. It is known only from the Western Ghats of India.

Key takeaways

Idionyx travancorensis belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Idionyx travancorensis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Idionyx travancorensis from memory before moving on to harder problems.

Reference excerpt

Idionyx travancorensis is a species of dragonfly in the family Idionychidae. It is known only from the Western Ghats of India.

Description and habitat It is a small dragonfly with emerald-green eyes. thorax metallic green. There is no humeral stripe. Laterally There is a narrow oblique stripe at the level of the spiracle and another on the hinder border of metepimeron. Beneath the side is black, bordered with yellow, and with a stripe of paler yellow at its middle. Abdomen is black. In segment 2, the ventral border and a narrow apical stripe in yellow. Segment 10 has a broad carina; but without a dorsal spine. Anal appendages are black. The male can be easily distinguished by the shape of its inferior anal appendage and the female by its safironated wings and conical vesicle. Fraser (1931) states that the species occurs from 3,000 - 4,000 ft in the Western Ghats and breeds in mountain streams. Nothing else is known of its habitat or ecology.

Worked examples

Example 1 — a first encounter with Idionyx travancorensis

Start with the simplest possible case. Write down what Idionyx travancorensis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Idionyx travancorensis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Idionyx travancorensis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Idionyx travancorensis

In research: Idionyx travancorensis appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Idionyx travancorensis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Idionyx travancorensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dragonfly stubs, IUCN Red List data deficient species, Idionychidae, so understanding it makes those chapters shorter.
In everyday life: Look for Idionyx travancorensis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
