Species in UPSC Prelims: about 5 marks every paper, and most of them aren't from the news
UPSC has asked about animals, birds or insects in every Prelims paper since 2016. What those 26 questions actually test, the trap most of them share, and a preparation plan built on them.
Most aspirants prepare for species questions by memorising whichever animals were in the news that year. The past papers suggest that’s the wrong bet. UPSC has asked about a particular animal, bird or insect in every Prelims paper since 2016, but most of those questions had nothing to do with the news.
This post looks at what the 26 questions have in common and turns it into a plan.
What the numbers say
Three things stand out.
It never skips a year. Every paper from 2016 to 2026 has had at least one species question, usually two or three.
It comes in waves. There were 5 questions in both 2023 and 2024, then 1 in 2025 and 2 in 2026. Don’t build your plan around a peak year, but don’t expect the area to disappear either.
The format keeps changing. All five “How many of the above are correct?” species questions came in 2023 and 2024. In 2025 and 2026 UPSC went back to classic statement sets. Either way, partial knowledge doesn’t help much, because each statement has to be judged on its own.
What UPSC is really testing
By our count, the 26 questions fall into four groups:
- Behaviour and biology: 11 questions. Who leads an elephant herd, which animals roll into a ball, which insect does the waggle dance, whether cheetahs roar.
- Where a species lives: 6. Gharials in the Chambal, the Asiatic lion found only in India, the indri in Madagascar.
- Species in the news: 5. The Kharai camel, Amur falcons at Doyang Lake, the Western hoolock gibbon.
- What kind of animal it is: 4. Frogmouths are birds, froghoppers are insects, and the Peacock tarantula is a spider, not a crustacean.
The largest group is general animal behaviour, not current affairs. Only 5 of 26 questions came straight from the news, although both 2026 questions did. A news-only notebook would have missed most of these marks.
The level of detail is also lower than most books suggest. No question asked for a scientific name, an exact population figure or a date. UPSC tests whether you understand an animal, not whether you memorised its fact sheet.
The trap most questions share
Most wrong options rely on something you have heard of. Kerala is famous for elephants, but Karnataka has the most. Kaziranga is famous for rhinos, but they also live wild in Nepal. Bhitarkanika is famous for crocodiles, but gharials live in the Chambal. A “frogmouth” sounds like a frog, and the Great Indian Hornbill is easily confused with the Great Indian Bustard.
When an option feels right because it’s famous, slow down. That’s usually where UPSC has set the trap.
How to prepare
1. Build a base in animal behaviour first. This is the biggest group, and it doesn’t change with the news cycle. Learn the standout behaviours: tool use, fungus-farming ants, communication like the bee’s dance, defences like rolling up, and social structures like the matriarch-led elephant herd.
2. Map species to places. For each important Indian species, know where it lives (region, river, forest or sanctuary) and whether it lives only in India. “Found naturally in India only” has come up more than once.
3. Keep a news notebook with five fields. For each species that appears in the news, note:
- where it lives in India
- whether it’s found only in India
- what kind of animal it is
- one unusual fact about its behaviour or biology
- what it’s often confused with
The last field matters most, because that’s where the trap usually is.
4. Solve the past questions before reading more. They show exactly how deep UPSC goes. Most aspirants over-prepare the details and under-prepare the basics.
What to skip: scientific names, population figures and IUCN Red List categories. IUCN status appears in the wording sometimes, but it has rarely been what decided the answer.
Two questions that show the pattern
2023 · Behaviour. Which organisms perform a waggle dance to show others the direction and distance of food? Honeybees. The trap was wasps, which look similar. This had nothing to do with the news: it’s pure animal behaviour. See the question
2017 · Where it lives. Where is the best place to see gharials in the wild? The Chambal River. The trap was Bhitarkanika, famous for a different reptile, the saltwater crocodile. See the question

Every one from 2016 to 2026, with the answer, an explanation and the trap in each.
