Reference excerpt

Sri Lanka is a tropical island situated close to the southern tip of India. The invertebrate fauna is as large as it is common to other regions of the world. There are about 2 million species of arthropods found in the world, and still it is counting. So many new species are discover up to this time also. So it is very complicated and difficult to summarize the exact number of species found within a certain region. This is a list of the ephemeropterans found from Sri Lanka.

Mayfly Phylum: Arthropoda Class: Insecta Order: Ephemeroptera Mayflies or shadflies are aquatic insects belonging to the order Ephemeroptera. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families. Mayflies are relatively primitive insects and exhibit a number of ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. They are aquatic insects whose immature stages (called "naiads" or "nymphs") live in fresh water, where their presence indicates a clean, unpolluted environment. They are unique among insect orders in having a fully winged terrestrial adult stage, the subimago, which moults into a sexually mature adult, the imago. In 1853, Walker first described about two species of mayflies from Sri Lanka. Then 1858, Hagen documented 8 more species from the country. The most useful taxonomic and other ecological aspects of mayflies of Sri Lanka came during 1960s and 1970s by Peters (1967) and Peters & Edmunds (1970). In 1965, Fernando described comprehensive work on mayflies. Through this, Hubbard and co-workers documented 46 species in 8 families from the country which is the most valuable source for present day as well. Currently there are 52 species of mayflies are reported from Sri Lanka, which belongs to 8 families.

Worked examples

Example 1 — a first encounter with List of Ephemeropterans of Sri Lanka

Start with the simplest possible case. Write down what List of Ephemeropterans of Sri Lanka 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 List of Ephemeropterans of Sri Lanka 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 List of Ephemeropterans of Sri Lanka 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 List of Ephemeropterans of Sri Lanka

In research: List of Ephemeropterans of Sri Lanka 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 List of Ephemeropterans of Sri Lanka 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: List of Ephemeropterans of Sri Lanka is common in secondary-school and first-year university syllabi. It links to neighbouring topics Insects of Sri Lanka, Lists of biota of Sri Lanka, Wildlife by country, so understanding it makes those chapters shorter.
In everyday life: Look for List of Ephemeropterans of Sri Lanka 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.
