Butterflies in July 2021 (2nd Half)

 The 2nd half of July witnessed several old and new butterflies emerging. 


Aw ! what an awl !

Plain Banded Awl (Hasora vitta vitta)

Like most awls, when they fly close-by you can actually hear their wing beats which sounded like a buzzing bee.



Tiger Palmfly (Elymnias nesaea lioneli)

This is the best photo of this species I have gotten so far.

Butterfly wings contain a series of living cells which function requires aa range of temperatures. Scientist have found that butterflies regulate their wing temperatures through both structural and behavioral adaptations.

Behavioral adaptation - research has found that butterflies at higher altitudes could warm up by dorsal basking i.e with their wings fully open or partially open. Sometimes you could also see them rotating their body to maximise the coverage.

Structural adaptation - engineers and biologist from Columbia University of Engineering & Applied Science found that butterfly wings are loaded with a network of mechanical and temperature sensors called androconial pads which allow butterflies to accurately determine the intensity and direction of sunlight.

Butterflies in July 2021 (1st Half)

The month of July saw just a few butterflies due to the rainy weather and the extended lockdown. Most of the photos here are those butterflies which appeared in late June and early July. Most of them were seen basically from nearby parks and gardens.

This skipper was once described by the literature as a common garden butterfly but nowadays I believe you can hardly see them.

Grass Demon (Udaspes folus)


It was seen on a periwinkle (Catharanthus roseus) flower which is located in my neighbourhood. 


So lucky that it stood there for a couple of minutes.



Many butterflies (especially rare ones) seldom open their wings but when one opens it wings, it's like a grand invitation for you to appreciate their beauty.


Nacaduba sanaya elioti (Jewel Four-Line Blue).  
To identify this small butterfly an expert had earlier alerted me of its 'tail-less' feature.  



Here's the underside of the Jewel Four-Line Blue




The one above had been identified by an expert as a male Jamides bochus nabonassa (Dark Cerulean).




Common Cerulean (Jamides celeno aelianus)




A female Abisara saturata kausambiodes (Malayan Plum Judy)




Arhopala perimuta perimuta (Yellowdisc Oakblue)




Athyma kanwa kanwa (Dot-dash Sergeant)



The above is a seldom seen female Athyma nefte subrata (Colour Sergeant)



Observing a butterfly ovipositing in your garden is a chance of a life time. Here is a common female Pygmy Grass Blue (Zizula hylax pygmaea) doing just that.

The female Pygmy Grass Blue was seen ovipositing on a young flower bud of a Ruellia squarrosa (Water Bluebell).


You can see one of its eggs here


Another one can be seen on the top flower bud.


To minimise the risk of losing all its eggs, it will spread it across all the young flower buds as seen from the above photos.



Tailed Jay (Graphium agamemnon agamemnon)

A common butterfly along the forest trails which is more often observed flying around than landing on a leaf.



Spotted Black Crow (Euploea crameri bremeri)



This is an uncommon 'Delieas' which is reported to be a migrating butterfly.

Red-based Jezebel (Delias pasithoe parthenope)




Malayan Sunbeam (Curetis santana malayica)

Check out its different antenna colors




 Fluffy Tit (Zeltus amasa maximminianus)




Common Imperial (Cherita freja frigga)




Pointed Palmfly (Elymnias penanga penanga) 

The above butterfly is a rather uncommon male which has a beautiful deep bluish purple on its forewing upperside.




Blue Posy (Drupadia scaeva scaeva)



Blue Posy (Drupadia scaeva scaeva) - female





The Malay Yeoman (Cirrochroa malaya malaya)

Trying to blend in with the color of the leaves.




A loving pair of Dark Banded Ace (Halpe ormenes vilasina)




Harlequin (Taxila haquinus haquinus)

There was once a campaign in Singapore to save its population in the island.



Here are a few common skippers which you might probably encounter

Swinhoe Ace (Halpe wantona)




Halpe pelethronix pelethronix (Peninsular Ace)




Pothantus omaha omaha (Lesser Dart)




Plain Tufted Lancer (Isma iapis iapis)




Oriens gola pseudolus (Common Dartlet)






A pristine looking Branded Imperial (Eooxylides tharis distanti)






Hypolimnas bolina (Great Eggfly)

Apparently there are two ssp of bolinas in this region i.e i) H. bolina bolina and ii) H. bolina jacintha. H. bolina bolina which is the 'original' ssp in this region was reportedly been displaced by H. bolina jacintha since about 30 years ago. It was also said that interbreeding between the ssp has occurred and that the female form has many variables.




I presumed the above is a H. bolina bolina as H. bolina jacintha is now quite uncommon.




Another H. bolina bolina - a female I presumed.




Lastly but not least, here is a common butterfly which you will encounter 


Common Five-Ring (Ypthima baldus newboldi)





Butterflies in April 2024 - Burara, Hasora et al

Looks like the month of April 2024 is filled with Hasora and Burara species. These species mainly appear at dawn or dusk where there are les...
