The butterfly survey, part of the Batu Caves Scientific Expedition (BCSE 2019), was to determine the list of butterflies of Batu Caves. It was carried out from December 2018 right through 2019 and results were presented at a one-day symposium. Overall, the BCSE is to determine the fauna and flora of Batu Caves with the aim of conserving them and thus protecting the environment of Batu Caves as a whole. This is important given that Batu Caves is a unique environment especially in the Kelang Valley, an outcrop of limestone hills reportedly 400 million years old (Shaharin Yusof 1997). The BCSE includes, apart from butterflies, surveys for flora, birds, snakes, dragonflies, bats, and other inhabitants of the numerous caves, as well as the geology of Batu Caves.
Given the importance of butterflies, among others, as pollinators, it is important to conserve them. This is especially so given that insects in general, worldwide, are losing biomass at the rate of 2.5% each year according to Sanchez-Bayo and Wyckhuys (2019). Blaming habitat destruction, especially due to intensive agriculture, and the use of synthetic pesticides for the decline of insects, they warn: “The conclusion is clear: unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades… The repercussions this will have for the planet’s ecosystems are catastrophic to say the least, as insects are at the structural and functional base of many of the world’s ecosystems…”
Total number of species identified for Batu Caves is 51 with a further nine identified only to the genus level or to the species level but with uncertainty i.e., altogether 60 species for Batu Caves. This is due to unavailable views, underside or upper side or just more views needed. And some species were difficult to identify from photos, for example the need to check the genitalia. These recorded species are from five families, with only the Rionididae absent. But I will not be surprised if more time were spent in the forest proper, up Batu Caves, it too would be recorded.
Some species of interest:
The Smaller Wood Nymph, Ideopsis gaura perakana, is recorded from lowland to highland, where, from personal experience, is common above Gohtong Jaya (~1000m) and Fraser’s Hill (~1200m). But I personally have never encountered it in any lowland forests even though I have been to many while photographing birds and butterflies in the past six years (it has been recorded in the lowland forest of Panti, Johor, but I have not encountered it even though have made quite a number of trips there. But there I have encountered the Common Tree Nymph, Idea stollis). It is common here with 5 records.
The Common Albatross, Appias albina, normally occurs at about 600 m according to Corbet and Pendlebury (2020) but possibly up to four individuals were recorded in Batu Caves in this survey.
Ceylon Blue Glassy Tiger, Ideopsis similis persimilis, occurs north from Kedah and Terengganu (Corbet and Pendlebury 1992) but quite common in Batu Caves with six and possibly eight records. Other than Batu Caves, there are few records outside its traditional range: Gopeng, Perak, by Singapore butterfliers (butterflycircle.blogspot.com), and in Kota Damansara Community Forest in a survey by Kirton and Phon (2012).
The Red Helen, Papilio helenus helenus, is uncommon in lowland, more common sub-montane and montane forests, has one record (photographed by Mike Chong). Out of my seven records of the Red Helen only one is from the lowland (three if we consider the hilly Gunung Telapa Buruk in Negri Sembilan).
Other notable butterflies are:
Common Sergeant, Athyma perius, (erratic in occurrence); White-banded Flat, Celaenorrhinus asmara asmara (uncommon); Yellow Grass Dart, Taractrocera archias quinta (historically rare, but even though now more widespread but still local in occurrence – Dr Kirton, pers comm).
The Julia Butterfly or Julia Heliconian, Dryas iulia, is very common in Batu Caves. It originates from the tropical Americas. But those found here originate from releases during weddings and religious celebrations for good luck from butterfly farms in Phuket, Thailand (see butterflycircle.blogspot.com). In Peninsular Malaysia, it was first recorded by Singapore butterfliers in Langkawi in 2009, and then in Subang Jaya 2015. My first record is from a Shah Alam park on 7 May 2017. In certain parts of Lembah Damai and Gua Damai it seems to be the dominant species. It thrives here because the larval host plants, two passionflowers, Passiflora foetida and Passiflora suberosa, are common. They too originate from the Americas.
A similar case is the Tawny Coster, Acraea terpsicore. It spreads south from its traditional range, India to Vietnam, reaching Perlis 1992, Petaling Jaya 2002 and four years later, Singapore and then Indonesia according to the blog Butterfly Circle. Its host plants are also the two passionflowers. The same also as another newcomer to the Peninsula, the Leopard Lacewing, Cethosia cyane (not in this checklist).
Given that the valleys and plateaus of the higher elevations of Batu Caves were not surveyed, there could be more species to be added to the list of 60 species, including from the family Riodinidae. Also, more would likely be added to the list if more visits were made, since every new trip to Lembah Damai part of Batu Caves brought up new species. Another limitation of the survey was the time of day (mornings) in which it was conducted. Visits at different hours of the day would likely record more species that are active at other times of the day.
The environment of Batu Caves must be conserved to protect its butterflies and other creatures as well as its unique limestone flora. It can be used to educate the public, especially students who can visit the various habitats to learn about the uniqueness of its fauna and flora. Some activities are already being held for this purpose, for example, cave visits in Lembah Damai area and the Dark Cave below the main temple cave. A photographic guide of the local butterflies has been made for the guides to use.
Here is the complete list of the identified butterflies to the species level of Batu Caves:

Table 1: An annotated checklist of butterflies recorded and identified with certainty from Batu Caves.
Some species could not be identified to the species level with certainty, mainly due to lack of underside or upperside view. It is sometimes difficult to identify species from photographs, especially species that are very similar to each other. Therefore, there may remain an element of doubt in the identification of some difficult species. These uncertain records are shown separately here in Table 2.
English Name | Scientific Name | Remarks | |
1 | A Crow | Euploea sp. | 6 individuals from Lembah Damai with variable but nearly similar underside require a photograph of the upperside to confirm the species. Probably all of the same species. |
2 | A Bush Brown | Mycalesis sp. Likely Mycalesis mineus macromalayana | Difficult to resolve the identity of this Mycalesis from a photograph. |
3 | A Cerulean | Jamides sp. | Needs upperside view. |
4 | A Flash | Rapala sp. | Difficult to identify from a photograph. |
5 | A Skipper, Flat | Pseudocoladenia sp. Likely Pseudocoladenia dan dhyana | Photograph does not show a typical Pseudocoladenia dan dhyana but is closest to it. |
6 | A Skipper, Dartlet | Oriens sp. | Needs underside view. |
7 | A Skipper | Potanthus sp. | Needs upperside view. |
8 | A Skipper, Small Branded Swift? | Pelopidas sp. Likely Pelopidas matthias | Needs other views. |
9 | A Skipper | Polytremis sp. Likely Polytremis lubricans lubricans | Needs other views, including underside. |

But any mistakes in the list are my responsibility.
I am grateful to Dr Kirton and Dr Phon for reading a draft of my symposium paper and for their comments and suggestions. Any shortcomings in the final version are of course mine.
