Mesembrina mystacea

Mesembrina mystacea 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 Mesembrina mystacea rather than just read about it. In short: Mesembrina mystacea is a fly belonging to the family Muscidae. It's commonly referred to as the moustached fly.

Key takeaways

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

Reference excerpt

Mesembrina mystacea is a fly belonging to the family Muscidae. It's commonly referred to as the moustached fly.

Distribution This species is present in the Palaearctic realm, from Fennoscandia south to Turkey and from the Atlantic seaboard across Eurasia to as far as Mongolia.

Description

Mesembrina mystacea can reach a length of 9–12 millimetres (0.35–0.47 in). These large, distinctive flies are beautifully colored in black, yellow-brown and white. They have a stout body. The long body hairs are mostly black, but they show a band of fine yellow-brown short hairs anteriorly across the thoracic dorsum and dense brown hairs on the abdomen, with white hairs at the edge. Metathorax and abdomen are shiny black. Eyes are bare. A large orange colouration is present on the base of the wings. The species exhibits a certain sexual dimorphism. In fact the anterior yellow-brown thoracic band of hairs is much narrower in the male than in the female. Moreover, in the male the mid tibiae are curved with longer hairs, while in the females they are straight and without longe hairs. These flies closely mimic certain Bombus species (bumblebees) (Apidae family). They are very similar to the hoverflies Criorhina berberina and Pocota personata (Syrphidae). Superficially they also resemble the hoverfly Volucella bombylans. M. mystacea is the only bumble-bee mimic among the Mesembrina species present in western Europe.

Biology and habitat Adults of Mesembrina mystacea can be found from June to September. The larvae feed on dung and dead material. In western Europe these flies are forest insects. They can be found in woodland or be grazed by cattle, in the Quercus, Fagus and Picea zones. This species belongs to insects with complete metamorphosis which involves a pupal stage.

Worked examples

Example 1 — a first encounter with Mesembrina mystacea

Start with the simplest possible case. Write down what Mesembrina mystacea 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 Mesembrina mystacea 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 Mesembrina mystacea 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 Mesembrina mystacea

In research: Mesembrina mystacea 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 Mesembrina mystacea 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: Mesembrina mystacea is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal taxa named by Carl Linnaeus, Insects described in 1758, Muscidae, so understanding it makes those chapters shorter.
In everyday life: Look for Mesembrina mystacea 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.
