Article #01: Scarab Beetles of Cornwall Gardens

Over the years, I have seen many species of Scarab beetles, however, to this day, Cornwall Gardens remains one of my favourite places to search for scarabs. Here is a documentation of all the species I have seen and photographed at the area. The area, and the hill, is demarcated in my first post,

I thought I would start with the most commonly encountered beetle, and move to the rarest. So, to start off, the most commonly encountered beetle is undoubtedly this chafer beetle, Adoretus Compressus. They can be observed feasting on the melastoma plants in great numbers at ‘The Hill’. many mating pairs can also be found most of the time.

Next, I would go with this brownish-coloured chafer beetle. They can be found on virtually every bush in the area if you search carefully, but in much lesser numbers than the Adoretus compressus chafer beetle.

Before yesterday, I would have gone with the Maladera chafer beetles for third place, however, after yesterdays’ huge ‘invasion’ of these Phyllophaga sp. beetles, i will go with them for now, as there was truly a massive number of them at the fig trees. I just hope it is not a one-time thing.

Next, the Maladera beetles. At first, I thought these guys were Maladera castanea, but after a closer look, it seems that there is a rather obvious split between two, possibly more species of Maladera chafer beetles in Singapore.

Next, the Apogonia cf. expeditionis chafer beetles. Up to today, I am not sure if there is more than one species that can be found at Cornwall Gardens.

Next, the Anomalla cf. pallida chafer beetle, which I have encountered several times, at the concrete well which leads to the drains underground.

The next place is a little tough, as there are a few beetles that I have only encountered once here. After some careful thought, I decided to go with this other Anomalla sp. chafer beetle, as I could have mistaken it for the Anomalla cf. pallida beetle shown above. It differs slightly in the shape of the body, and the colour of the head.

Next, this other Adoretus sp. chafer beetle, which I may sometimes have mistaken for the second species on the list, the other Adoretus sp. beetle.

Next, this huge Anomalla sp. Chafer Beetle, which has unfortunately lost one of its front two legs.

The last Scarab beetle on the list is a surprise. it is a small 8mm dung beetle, which was identified as Onthophagus sp. Cool!

And that wraps up the chafer beetles I have seen at the place. Now that you have seen, if you are interested, go to the place in the night and take a look around the area, especially ‘The Hill’!
