Olinga fumosa

Olinga fumosa 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 Olinga fumosa rather than just read about it. In short: Olinga fumosa is a species of caddisfly belonging to the family Conoesucidae. The species was first described by Keith Arthur John Wise in 1958, and is endemic to New Zealand.

Key takeaways

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

Reference excerpt

Olinga fumosa is a species of caddisfly belonging to the family Conoesucidae. The species was first described by Keith Arthur John Wise in 1958, and is endemic to New Zealand.

Taxonomy The species was identified by Wise in 1958, based on a specimen collected from Waitati in 1917 by C. E. Clarke. No further specimens of the species were discovered until entomologist Brian H. Patrick discovered further specimens in 1992. Patrick confirmed that the species was distinct from other members of Olinga, based on behavioural differences and the apparent inability to hybridise with O. feredayi.

Description Wise's original text (the type description) reads as follows:

ANTERIOR WING fuscous; scales of longitudinal fold and sub-terminal furrow ochreous, Membranes of both anterior and posterior wings fumose. Spurs 2.2.4. Length of anterior wing, 8 mm (0.31 in). Genitalia♂. Margin of ninth segment with a pair of long dorsal processes with a wart on each side and a pencil of hairs below the wart. Dorsal portion of ninth segment produced downwards posteriorly with upper penis-cover in form of two short processes arising distally below. Penis membranous. Inferior appendages broad at the base and twisted over dorsally towards the apex, each with a long, sinuous, pointed spine arising from its extreme base. These spines pass on each side of the penis and terminate above it between the penis-cover processes. Seventh sternite with a short, broad process. Males have a wingspan of 18.5 mm (0.73 in), with females larger at 22 mm (0.87 in). Wise noted that the species was visually similar to O. feredayi, but could be identified by O. fumosa being smaller, darker in colour, differences in genitalia and the seventh sternite.

Distribution and habitat The species is endemic to New Zealand, found in the vicinity of Dunedin in the Otago Region and South Canterbury on the South Island of New Zealand.

Worked examples

Example 1 — a first encounter with Olinga fumosa

Start with the simplest possible case. Write down what Olinga fumosa 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 Olinga fumosa 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 fumosa 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 fumosa

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