Libelloides coccajus

Libelloides coccajus 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 Libelloides coccajus rather than just read about it. In short: Libelloides coccajus, the "owly sulphur", is an owlfly species belonging to the family Ascalaphidae, subfamily Ascalaphinae. Distribution This rare insect is present in France, Czech Republic, Germany, Italy, Spain and Switzerland.

Key takeaways

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

Reference excerpt

Libelloides coccajus, the "owly sulphur", is an owlfly species belonging to the family Ascalaphidae, subfamily Ascalaphinae.

Distribution This rare insect is present in France, Czech Republic, Germany, Italy, Spain and Switzerland.

Habitat These owlflies mainly inhabit areas with tall grass and sunny rocky slopes, at an elevation up to 1,500 metres (4,900 ft) above sea level. They have been sighted at elevations of up to 1,800 metres (5,900 ft) on the French/Italian border in the high Susa Valley.

Description The adults reach 25 millimetres (0.98 in) of length, with a wingspan of 45–55 millimetres (1.8–2.2 in). The body is black and quite hairy. The eyes are large and bulging; the antennae are long and clubbed. The wings do not have scales and are partly transparent, with bright yellow areas in the first third, dark brown on the external side. An elongated black area is present towards the end of the posterior edge of the wing. The venation is black. The wings are held spread at rest, as in dragonflies. This species is rather similar to Libelloides lacteus.

Taxonomy The Libelloides italicus type in the University of Copenhagen Zoological Museum does not correspond to any endemic species of Ascalaphidae living exclusively in the Italian Peninsula and it is now considered to be a junior synonym of Libelloides coccajus.

Biology Adults can be encountered from April through July. They are diurnal predators of other flying insects. Eggs are laid in groups on stems of herbaceous plants. Larvae are fearsome predators too. They lie on the soil surface waiting for prey. They live for about two years.

Worked examples

Example 1 — a first encounter with Libelloides coccajus

Start with the simplest possible case. Write down what Libelloides coccajus 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 Libelloides coccajus 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 Libelloides coccajus 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 Libelloides coccajus

In research: Libelloides coccajus 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 Libelloides coccajus 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: Libelloides coccajus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ascalaphidae, Insects described in 1775, Libelloides, so understanding it makes those chapters shorter.
In everyday life: Look for Libelloides coccajus 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.
