Simona retracta

Simona retracta is a science 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 Simona retracta rather than just read about it. In short: Simona retracta is a species of cicada, also known as the Charleville Eremophila cicada, in the true cicada family, Cicadettinae subfamily and Cicadettini tribe. The species is endemic to Australia.

Key takeaways

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

Reference excerpt

Simona retracta is a species of cicada, also known as the Charleville Eremophila cicada, in the true cicada family, Cicadettinae subfamily and Cicadettini tribe. The species is endemic to Australia. It was described in 2015 by entomologists Anthony Ewart, Lindsay Popple and David C. Marshall.

Description The length of the forewing is 18–23 mm.

Distribution and habitat The species is only known from the vicinity of Charleville in South West Queensland. The associated habitat is open shrubland with Eremophila gilesii shrubs.

Behaviour Adult males may be heard in January and February, clinging to the stems of shrubs, emitting complex rattling, chirping and spluttering calls.

Worked examples

Example 1 — a first encounter with Simona retracta

Start with the simplest possible case. Write down what Simona retracta claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Simona retracta 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 Simona retracta 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 Simona retracta

In research: Simona retracta appears in science 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 Simona retracta 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: Simona retracta is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cicadas of Australia, Cicadettinae stubs, Insects described in 2015, so understanding it makes those chapters shorter.
In everyday life: Look for Simona retracta 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.
