This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Habrodais grunus rather than just read about it. In short: Habrodais grunus, the golden hairstreak, is a butterfly in the family Lycaenidae. It is found in North America in southern Arizona, Oregon, California, Washington, Idaho, and Mexico.

Key takeaways

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

Reference excerpt

Habrodais grunus, the golden hairstreak, is a butterfly in the family Lycaenidae. It is found in North America in southern Arizona, Oregon, California, Washington, Idaho, and Mexico. The habitat consists of oak woodland, canyons and mountain ridges.

The wingspan is 25–32 mm. Adults have a golden-brown coloration on their body, and have a short tail. Adults are on wing from June to September in one generation per year. Adults are primarily crepuscular, being most active in the early morning and evening, while resting in shaded areas for the remainder of the day. They feed on moisture from various sources and possibly also feed on aphid honeydew or other exudates. They spend the majority of their time above in the trees, only descending for nectar. The larvae, which hatch from eggs laid on host twigs, feed on the young leaves of Chrysolepis chrysophylla, Quercus chrysolepis, Quercus vaccinifolia and Lithocarpus densiflorus. The caterpillars are blue-green in color on their body, and have silver hairs. In their subsequent pupa stage, they are bluish-green with brown dots. The caterpillars will mature to their adult stage in the span of approximately 2 weeks.

Worked examples

Example 1 — a first encounter with Habrodais grunus

Start with the simplest possible case. Write down what Habrodais grunus 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 Habrodais grunus 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 Habrodais grunus 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 Habrodais grunus

In research: Habrodais grunus 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 Habrodais grunus 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: Habrodais grunus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butterflies described in 1852, Lycaenidae of South America, Lycaenidae stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Habrodais grunus 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.
