Pitthea famula

Pitthea famula 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 Pitthea famula rather than just read about it. In short: Pitthea famula is a species of moth in the family Geometridae. It was first described by Dru Drury in 1773 from Calabar, in what is now Nigeria.

Key takeaways

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

Reference excerpt

Pitthea famula is a species of moth in the family Geometridae. It was first described by Dru Drury in 1773 from Calabar, in what is now Nigeria. It is found in Angola, Benin, Cameroon, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea (Bioko), Nigeria, Sierra Leone and Zambia.

Description Upperside: antennae long and pectinated (comb like). Thorax spiral. Neck orange. Thorax and abdomen dusky grey. Anterior wings about halfway from the tips black, but at the base are of a pellucid (transparent) white; being surrounded along the anterior edge and part of the posterior with black; an oblong white spot is placed near the tips on the black part. Posterior wings black and white; the white entirely surrounded by the black, which on the anterior and abdominal edges is very narrow. Underside: palpi orange, black at the tips. Neck, breast, and sides orange. Feet black. Thighs white. Abdomen white, annulated with dusky grey. Anterior wings as on the upperside, the black parts being of a russet hue. Posterior wings differ a little, the white part running down to the middle of the external edges, with a white spot at the upper corners. Margins of the wings entire. Wingspan 2 inches (50 mm).

Worked examples

Example 1 — a first encounter with Pitthea famula

Start with the simplest possible case. Write down what Pitthea famula 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 Pitthea famula 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 Pitthea famula 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 Pitthea famula

In research: Pitthea famula 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 Pitthea famula 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: Pitthea famula is common in secondary-school and first-year university syllabi. It links to neighbouring topics Descriptions from Illustrations of Exotic Entomology, Ennominae, Ennominae stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Pitthea famula 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.
