Locustopsidae

Locustopsidae 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 Locustopsidae rather than just read about it. In short: Locustopsidae is an extinct family of orthopterans known from the Mesozoic. They represent some of the oldest members of the suborder Caelifera.17 Members of the family closely resemble living grasshoppers of the superfamily Acridoidea in the shape of the body and wing venation.

Key takeaways

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

Reference excerpt

Locustopsidae is an extinct family of orthopterans known from the Mesozoic. They represent some of the oldest members of the suborder Caelifera.17 Members of the family closely resemble living grasshoppers of the superfamily Acridoidea in the shape of the body and wing venation. It is one of two families consistently placed in the superfamily Locustopsoidea, alongside the Triassic family Locustavidae, suggested to be united by characters of the wing, including "three-branched MA [M] and the branched MP+CuA [CuA+CuPaα] of the tegmina, as well as the branched MA of the hind wings". Locusopsoids have been suggested as some of the most basal members of Caelifera.323-345,539 Locustopsoidea has been proposed as the ancestral stock from which modern Tetrigoidea, Eumastacoidea, and Acridoidea arose. There are about 17 genera and more than 60 described species in Locustopsidae.

Genera These 17 genera belong to the family Locustopsidae:

Worked examples

Example 1 — a first encounter with Locustopsidae

Start with the simplest possible case. Write down what Locustopsidae 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 Locustopsidae 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 Locustopsidae 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 Locustopsidae

In research: Locustopsidae 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 Locustopsidae 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: Locustopsidae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Acrididea, Prehistoric insect families, Prehistoric insect stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Locustopsidae 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.
