Insect pins

Insect pins 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 Insect pins rather than just read about it. In short: Insect pins are used by entomologists for mounting collected insects. They can also be used in dressmaking for very fine silk or antique fabrics.

Key takeaways

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

Reference excerpt

Insect pins are used by entomologists for mounting collected insects. They can also be used in dressmaking for very fine silk or antique fabrics. As standard, they are 38 millimetres (1.5 in) long and come in sizes from 000 (the smallest diameter), through 00, 0, and 1, to 8 (the largest diameter). The most generally useful size in entomology is size 2, which is 0.46 millimetres (0.018 in) in diameter, with sizes 1 and 3 being the next most useful. They were once commonly made from brass or "German silver", but these would corrode from contact with insect bodies and are no longer commonly used. Instead they are nickel-plated brass, yielding "white" or "black" enameling, or even made from stainless steel. Similarly, the smallest sizes from 000 to 1 used to be impractical for mounting until plastic and polyethylene became commonly used for pinning bases. There are also micro-pins, which are 10–15 millimetres (0.39–0.59 in) long. minutens are headless micropins that are generally only made of stainless steel, and used for double-mounting. The insect is mounted on the minutum, which is pinned to a small block of soft material, which is in turn mounted on a standard, larger, insect pin.

Worked examples

Example 1 — a first encounter with Insect pins

Start with the simplest possible case. Write down what Insect pins 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 Insect pins 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 Insect pins 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 Insect pins

In research: Insect pins 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 Insect pins 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: Insect pins is common in secondary-school and first-year university syllabi. It links to neighbouring topics Collecting, Entomology equipment, Fasteners, so understanding it makes those chapters shorter.
In everyday life: Look for Insect pins 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 Insect pins in simple terms?

Insect pins are used by entomologists for mounting collected insects. They can also be used in dressmaking for very fine silk or antique fabrics.

Why does Insect pins 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 Insect pins?

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.
