Golden Royal in an urban estate

Hi all,

When you least expect it, you get rewarded. Heard it before? Right!!!

Simon Chan and I were out again this morning surveying an urban estate in Bukit Timah area. It had just drizzled and the weather was barely clearing up. We thought it is time to take a break and look at plants.

Just then a blue iridescent lycaenid appears...'What's that?' Scarce Silverstreak (Iraota rochana). Hey that's nice!
Then I notice another lycaenid high up. Simon see a Branded Imperial high up? Gosh no...Golden Royal (Pseudotajuria donatana).
OMG! OMG!

We managed to take some shots when it came down. Tattered but cooperative individual. Hurrah!

Golden Royal is one among the 20 critically endangered butterfly species in Singapore. And it was really good to see this individual in an urban estate...confirming it as a likely urban adaptor. Hopefully this will warrant it a brighter future.

Cheers,
Anuj

Yes, Anuj, good things come to those who wait and watch! You have been rewarded with 2 Golden Royals - one at Bt Brown & now at an urban estate. It is really heartening to know that this rare butterfly is still around especially in an urban estate - yes, if they can adapt they will have a better chance of survival.... do you know what are their host and food plants?

Amy,
Thanks for the compliment! The larval host plant should a mistletoe. Only recorded it nectar feeding on Ixora species.

Laurence,
According to Singapore Red Data Book 2008 (2nd ver), here are the following 20 critically endangered butterfly species -
1. Common Jay (Graphium doson)
2. Mangrove Tree Nymph (Idea leuconoe)
3. Malayan Crow (Euploea camaralzeman)
4. Pointed Palmfly (Elymnias penanga)
5. Scarce Six Ring (Ypthima fasciata)
6. Common Duffer (Discophora sondaica)
7. Plain Lacewing (Cethosia penthesilea)
8. Danaid Eggfly (Hypolimnas misippus)
9. White Tipped Baron (Euthalia merta)
10. Courtesan (Euripus nyctelius)
11. Black Rajah (Charaxes solon)
12. Moth Butterfly (Liphyra brassolis)
13. Common Pierrot (Castalius rosimon)
14. Spotted Silverstreak (Iraota distanti)
15. Pygmy Posy (Drupadia rufotaenia)
16. White Royal (Pratapa deva)
17. Banded Royal (Rachana jalindra)
18. Golden Royal (Pseudotajuria donatana)
19. Silver Royal (Ancema blanka)
20. Detritus Palmer (Zela storeyi)

All five star species :dance:

In Singapore's context, to classify a species as threatened (including critically endangered), we mainly look at population density, distribution (in the context of no. of locations known) and rarity.

Cheers,
Anuj

Today, even the light of a moth is rare, as the sun after the rainbow is obtained.
