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 two million species of arthropods found in the world, and still is counting. The following list is about confirmed hemipterans recorded in Sri Lanka, though many new unconfirmed sightings are existent.

Hemipterans Phylum: Arthropoda Class: Insecta Order: Hemiptera The Hemiptera order of insects includes the insects commonly known as the true bugs. The order includes planthoppers, leafhoppers, shield bugs, cicadas, aphids. More than 70,000 species are distributed worldwide. Most hemipterans are plant sap feeders, some are parasitic, while the rest are predators who attack small insects and small invertebrates. Most species are terrestrial and a few are aquatic. Hemipterans are hemimetabolous, where young are similar to adults in the morphology. Hemipterans are economically important insects, where most of them are agricultural pests and vertebrate parasites. The following list provide the hemipterans currently identified in Sri Lanka. Sri Lanka is known to be home for 794 species of hemipterans included to 71 families. Detailed work of Sri Lankan hemipterans are recorded in book Catalogue of Hemiptera of Sri Lanka. Sri Lanka comprises 74 species in 46 genera and 6 families of aphids within order Hemiptera. Two endemic aphid species found on Sri Lanka. Many researches have been carried out by different hemipteran families by local and overseas experts. In 2009, M. Prashanthini and M. Vinobaba of Eastern University of Sri Lanka carried out experiments on mealybugs and identified 38 species of mealybugs from Sri Lanka with new exotic species. Un updated systematic catalogue of cicadas of South Asia have been published in 2016. According to that, 22 species of cicadas were recorded from Sri Lanka. Chopra and Rustagi in 2012 published the characters of the subfamily Chauliopinae from India and Sri Lanka. In 2012, B. Vasantharaj David compiled the checklist and diversity of whiteflies of Sri Lanka with new records of seven species and new Pealius species from Sri Lanka. Fourteen species belonging to eight genera of soft scales were identified with two introduced species from Sri Lanka. The provisional checklist of the leafhoppers in Sri Lanka have been compiled by Dr. Rajendramani Gnaneswaran of the department of zoology, University of Jaffna. With her revision, 257 leafhopper species belonging to 120 genera have been identified from Sri Lanka.

Worked examples

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

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

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