Sclerodermus domesticus

Sclerodermus domesticus 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 Sclerodermus domesticus rather than just read about it. In short: Sclerodermus domesticus, also known as Scleroderma domesticus, Scleroderma domesticum, Scleroderma domestica or "antiquarian's friend", is a species of flat wasp in the insect genus Sclerodermus. It was first described by Pierre André Latreille in 1809.

Key takeaways

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

Reference excerpt

Sclerodermus domesticus, also known as Scleroderma domesticus, Scleroderma domesticum, Scleroderma domestica or "antiquarian's friend", is a species of flat wasp in the insect genus Sclerodermus. It was first described by Pierre André Latreille in 1809.

Description

Sclerodermus domesticus preys on Coleoptera including Anobium punctatum, Stegobium paniceum, Lasioderma serricorne, Hylotrupes bajulus and Nicobium castaneum, or occasionally Lepidoptera. Males have wings but lack a stinger. Females are 2–5 mm long; they have a stinger but lack wings. They are black/brown, and have the appearance of ants. Females enter woodworm holes, paralyze the woodworm larvae with the venom of the stinger and lay their eggs in the corpses, which form the food for the S. domesticus larvae. This behavior leads to the common name of "antiquarian's friend".

Distribution and habitat

S. domesticus is a cosmopolitan species. It prefers mild weather. There are reports of the species in Spain, Italy, France, Portugal, (Germany), United Kingdom, former Yugoslavia, Near East, United States and Costa Rica. It can be found inside homes, mostly in old furniture, harboring woodworms. Stings are painful and can cause rash or dermatitis.

Worked examples

Example 1 — a first encounter with Sclerodermus domesticus

Start with the simplest possible case. Write down what Sclerodermus domesticus 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 Sclerodermus domesticus 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 Sclerodermus domesticus 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 Sclerodermus domesticus

In research: Sclerodermus domesticus 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 Sclerodermus domesticus 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: Sclerodermus domesticus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chrysidoidea, Chrysidoidea stubs, Parasitic infestations, stings, and bites of the skin, so understanding it makes those chapters shorter.
In everyday life: Look for Sclerodermus domesticus 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.
