Lucinia cadma

Lucinia cadma 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 Lucinia cadma rather than just read about it. In short: Lucinia cadma is a species of brush-footed butterfly (family Nymphalidae). It was first described by Dru Drury in 1773 from Jamaica.

Key takeaways

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

Reference excerpt

Lucinia cadma is a species of brush-footed butterfly (family Nymphalidae). It was first described by Dru Drury in 1773 from Jamaica. Distinct subspecies are found on other Caribbean islands.

Description Upper side: antennae black. Head, thorax, and abdomen dark brown. Wings tawny yellow. The anterior having the extreme parts, near the tips, black; with two yellowish spots thereon, joining the anterior edges; also a round black spot situated at the lower corners on the posterior edges. Posterior wings immaculate, except a black streak placed on the anterior edges next the upper corners. Under side: tongue black. Breast, legs, and abdomen ash-coloured. The superior wings marked and coloured as on the upper side, but less distinctly. Posterior wings tawny orange, having a broad ash-coloured bar crossing them from the anterior to the abdominal edges. On this bar are placed two eyes, with double pupils; the lower one being of a fine blue with a yellow iris; the upper one, next the anterior edges, blue and black, with a brown iris. Margins of the wings dentated. Wing-span 2 inches (50 mm).

Subspecies Lucinia cadma cadma (Jamaica) Lucinia cadma albomaculata Rindge, 1955 (Bahamas) Lucinia cadma sida Hübner, [1823] (Cuba) Lucinia cadma torrebia (Ménétriés, 1832) (Haiti)

Worked examples

Example 1 — a first encounter with Lucinia cadma

Start with the simplest possible case. Write down what Lucinia cadma 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 Lucinia cadma 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 Lucinia cadma 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 Lucinia cadma

In research: Lucinia cadma 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 Lucinia cadma 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: Lucinia cadma is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biblidinae, Biblidinae stubs, Butterflies described in 1773, so understanding it makes those chapters shorter.
In everyday life: Look for Lucinia cadma 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.
