Hemiargus ceraunus

Hemiargus ceraunus is a biology 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 Hemiargus ceraunus rather than just read about it. In short: Hemiargus ceraunus, the Ceraunus blue, is a species of butterfly in the family Lycaenidae. The species was first described by Johan Christian Fabricius in 1793.

Key takeaways

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

Reference excerpt

Hemiargus ceraunus, the Ceraunus blue, is a species of butterfly in the family Lycaenidae. The species was first described by Johan Christian Fabricius in 1793. It is found in the southwestern United States, southern Texas, Florida and the Florida Keys south through the West Indies, Mexico and Central America to South America. Strays may be found in North Carolina, Missouri, Kansas and Nevada. The habitat consists of open woodland, desert scrub, dunes, pastures, road edges and vacant lots.

The wingspan is 20–30 mm. Adults are on wing year round in Texas and southern Florida and in late summer in other parts of the range. Adults feed on flower nectar. The larvae feed on the flowers and seedpods of various woody legumes, including Chamaecrista fasciculata, Abrus precatorius and Prosopis species.

Worked examples

Example 1 — a first encounter with Hemiargus ceraunus

Start with the simplest possible case. Write down what Hemiargus ceraunus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Hemiargus ceraunus 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 Hemiargus ceraunus 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 Hemiargus ceraunus

In research: Hemiargus ceraunus appears in biology 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 Hemiargus ceraunus 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: Hemiargus ceraunus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butterflies described in 1793, Butterflies of Central America, Butterflies of North America, so understanding it makes those chapters shorter.
In everyday life: Look for Hemiargus ceraunus 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.
