The Perlis Pansy
The Perlis Pansy (Junonia lemonias) is more often called the Lemon Pansy.

The Perlis Pansy and other Pansies
(Published in the Malayan Naturalist, Vol 41 Nos 3 & 4, May 1988. This was sent as a Letter to the Editor but was instead used, to my surprise, in the magazine's PhotoFeature section.)

I REFER TO the article "The Perlis Pansy Comes to Town" by Basri K. Jemadi and Hugh Storey, reporting on their sighting of Precis* lemonias in January-February (Malayan Naturalist, August 1987).
 The Perlis Pansy has indeed come to town and appeared to have made a home for itself at Bukit Kiara, Damansara, the site of our future national arboretum**. The first time I saw this butterfly was in mid-June 1984, during a Sunday morning nature walk led by Dr Kiew Bong Heang to Bukit Kiara and I managed to take several pictures of it. (See how rewarding these MNS outings can be!)
 Being new to the hobby of butterfly-watching at that time, I could not identify the species. Later, from the few shots that I got, I made it out to be P. lemonias. And was I surprised to find that it was P. lemonias!
 W.A. Fleming's "Butterflies of West Malaysia and Singapore" gives the distribution of this species as Perak, Penang, L.K. (i.e. the Langkawi islands and Kedah, north of the Kedah River, and Perlis). "The Butterflies of the Malay Peninsula" by A.S. Corbet and H.M. Pendlebury states that P. lemonias "is almost confined to the Langkawi Islands and north Kedah... and this species is not found south of Penang."
 Excited by this discovery, I wrote to Lt. Col. J.N. Eliot at the end of 1984. He gave this information in his reply:
 "Butterflies tend to go through cycles of abundance and scarcity, and the limit of their range expands and contracts depending upon small and little-understood changes in environment, climate, etc. Most Precis species feed as larvae on weeds of cultivation and secondary growth; in Hong Kong the food plant of lemonias is Lepidagathis incurva (Acanthaceae). This habit makes their spread comparatively easy when conditions are favourable."
 So we see the Perlis Pansy has migrated south from Perlis, Kedah and Penang to Perak, Pahang and the Klang Valley. Whether it will move further down to Johore and across the Causeway remains to be seen. (Johore and Singapore have their own endemic Precis species, P. hedonia.)
 Two weeks after that MNS outing, I returned to Bukit Kiara to get more pictures of the Perlis Pansy
Junonia (Precis) lemonias (2) and I found many of the species in an overgrown area in this old rubber estate*** (near some old sheds that were being demolished). I made a third trip to the area in November 1984 and found an even greater number than on the two previous occasions. This colony of P. lemonias was thriving very well.
 However, I have not gone back to Bukit Kiara since then and I understand from workers who were then clearing the place that the area is off-limits.
 If the Perlis Pansy were to bring with it the pronounced dry spells of Perlis/Kedah to the Klang Valley, we could perhaps see an interesting characteristic of the Precis species, i.e. the occurrence of seasonal variation. What we usually encounter are the wet-season forms; the dry-season forms, described as having more sharply angled wings and cryptic patterns resembling a dead leaf on the underside, occur only during the dry season of the northern region from December to February.
 Another Pansy Butterfly ~ the sexually dimorphic P. orithya (the Blue Pansy) ~ was also plentiful at Bukit Kiara, in a clearing along the food path heading from the old labour line into the estate. Other Precis species occurring in Peninsular Malaysia are P. iphita (the Chocolate Soldier), P. atlites (the Grey Pansy) and P. hierta, which is found only in Langkawi.
 * All species in this group of butterflies have now been placed in the genus Junonia.
 ** That area where we had the nature walk is now occupied by a park and a large golf course. The national arboretum, I have been told, occupies a different part of Bukit Kiara.
 *** Bukit Kiara was covered by old rubber trees at that time. Most of Damansara, in fact, was covered by rubber estates and oil palm plantations at one time, but these had been progressively making way for housing estates and townships to accommodate the growing population of Kuala Lumpur and the Klang Valley.
