Strigiphilus

Strigiphilus 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 Strigiphilus rather than just read about it. In short: Strigiphilus is a genus of chewing lice in the suborder Ischnocera. It was circumscribed in 1910 by Eric Mjöberg.

Key takeaways

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

Reference excerpt

Strigiphilus is a genus of chewing lice in the suborder Ischnocera. It was circumscribed in 1910 by Eric Mjöberg.

Taxonomic history Mjöberg initially circumscribed Strigiphilus as a subgenus of the genus he referred to as Docophorus (now known as Philopterus). In a 1966 paper, Theresa Clay recognized 29 species and grouped them into these nine species groups:

S. crenulatus group (Giebel, 1874) S. cursitans group (Nitzsch, 1861) - largest number of species S. cursor group (Burmeister, 1838) S. heterocerus group (Grube, 1851) S. ketupae group Emerson & Elbel, 1957 S. macrogenitalis group Emerson & Elbel, 1957 S. rostratus group (Burmeister, 1838) S. siamensis group Emerson & Elbel, 1957 S. strigis group (Pontoppidan, 1763)

Hosts Strigiphilus is the only genus of the Ischnocera to exclusively parasitize owls.

Species As of 2017, about 50 species of Strigiphilus are known, including Strigiphilus garylarsoni Clayton, 1990. (cursitans group)

Worked examples

Example 1 — a first encounter with Strigiphilus

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

In research: Strigiphilus 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 Strigiphilus 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: Strigiphilus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lice, Louse stubs, Parasites of birds, so understanding it makes those chapters shorter.
In everyday life: Look for Strigiphilus 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 Strigiphilus in simple terms?

Strigiphilus is a genus of chewing lice in the suborder Ischnocera. It was circumscribed in 1910 by Eric Mjöberg.

Why does Strigiphilus matter?

Because it connects several science 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 Strigiphilus?

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.
