Permotipula

Permotipula 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 Permotipula rather than just read about it. In short: Permotipula is an extinct monotypic genus of protodipteran insect which contains a single species Permotipula patricia. The only specimen of Permotipula was found in Late Permian strata of the Newcastle Coal Measures between the towns of Belmont and Warners Bay on the eastern side of Lake Macquarie, New South Wales, Australia and named by Robert J.

Key takeaways

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

Reference excerpt

Permotipula is an extinct monotypic genus of protodipteran insect which contains a single species Permotipula patricia. The only specimen of Permotipula was found in Late Permian strata of the Newcastle Coal Measures between the towns of Belmont and Warners Bay on the eastern side of Lake Macquarie, New South Wales, Australia and named by Robert J. Tillyard in 1929 in honour of his wife Patricia Tillyard. The specimen consisting of a single well preserved wing, was considered lost after the death of Tillyard in 1937. The loss of the specimen and the mention by Tillyard of a second insect fossil from the same site, later described as Robinjohnia tillyardi resulted in much confusion regarding the taxonomic affiliations of P. patricia. Robinjohnia, a four winged insect which is now placed in the order Mecoptera. The P. patricia type specimen was found in the Tillyard collection which is housed at the British Museum and reexamined by R. Willmann in a 1989 paper. A second species, P. borealis was named by O.M. Martynova in 1961 from a small wing specimen found in the Kuznetsk Basin, Russia. This species was moved, however, in 1989 by R. Willmann to the monotypic genus Permila and is now considered a probable early mecopteran.

Worked examples

Example 1 — a first encounter with Permotipula

Start with the simplest possible case. Write down what Permotipula 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 Permotipula 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 Permotipula 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 Permotipula

In research: Permotipula 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 Permotipula 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: Permotipula is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 1929, Monotypic prehistoric insect genera, Permian insects, so understanding it makes those chapters shorter.
In everyday life: Look for Permotipula 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.

Frequently asked questions

What is Permotipula in simple terms?

Why does Permotipula matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Permotipula?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
