Reference excerpt

Philopotamus montanus, common name yellow spotted sedge, is a species of caddisfly belonging to the family Philopotamidae.

Hagen, 1860

Distribution and habitat This species is native to Europe. It extends over whole Europe eastwards to Northwestern and Northern Russia. The aquatic stages of Philopotamus montanus can be found mainly in small rivers in uplands, in brooks and rivulets and in stony streams, often with rapids, as this species prefers high current velocities.

Description

Philopotamus montanus can reach a body length of about 4–9 mm (0.16–0.35 in), with a wingspan of about 12–20 mm (0.47–0.79 in). These medium sized caddisflies are usually light brown or yellowish colored, with many dark brown spots.

Biology Philopotamus montanus has one generation a year (univoltine). Larvae build long, tubular nets attached to rocks. They are filter-feeders, mainly feeding on small, particulate matter, fine particles and diatoms. Adults of these caddisflies are on the wing from February to October.

Worked examples

Example 1 — a first encounter with Philopotamus montanus

Start with the simplest possible case. Write down what Philopotamus montanus 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 Philopotamus montanus 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 Philopotamus montanus 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 Philopotamus montanus

In research: Philopotamus montanus 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 Philopotamus montanus 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: Philopotamus montanus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Caddisflies, Insects described in 1813, Insects of Europe, so understanding it makes those chapters shorter.
In everyday life: Look for Philopotamus montanus 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.
