Olinga (caddisfly)

Olinga (caddisfly) 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 Olinga (caddisfly) rather than just read about it. In short: Olinga is a genus of caddisflies belonging to the family Oeconesidae. The genus was described by Robert McLachlan in 1868, revising the genus name in 1894.

Key takeaways

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

Reference excerpt

Olinga is a genus of caddisflies belonging to the family Oeconesidae. The genus was described by Robert McLachlan in 1868, revising the genus name in 1894. All known species of Olinga are endemic to New Zealand.

Taxonomy Robert McLachlan originally described the genus in 1868 under the name Olinx, naming Olinx feredayi as the type species. In 1894 he revised the name of the genus as Olinga, describing this change as "necessary, and under rather peculiar circumstances" as German entomologist Arnold Förster had proposed Olynx for another genus in 1856, which other authors had been rendering as Olinx since 1858, thus leading McLachlan to erroneously conclude that his name was preoccupied. The genus was monotypic until 1958, when Keith Arthur John Wise described Olinga fumosa. Phylogenetic analysis indicates that Olinga forms a clade with the genera Alloecentrella, Beraeoptera, Confluens, Pycnocentria and Pycnocentrodes.

Distribution The genus is found in New Zealand.

Worked examples

Example 1 — a first encounter with Olinga (caddisfly)

Start with the simplest possible case. Write down what Olinga (caddisfly) 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 Olinga (caddisfly) 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 Olinga (caddisfly) 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 Olinga (caddisfly)

In research: Olinga (caddisfly) 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 Olinga (caddisfly) 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: Olinga (caddisfly) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Caddisflies, Caddisflies of New Zealand, Caddisfly genera, so understanding it makes those chapters shorter.
In everyday life: Look for Olinga (caddisfly) 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.
