Neo Teo

Location:
Neo Teo
Species seen:
Anisoptera--Dragonflies
Libellulidae
  • Diplacodes trivialis
  • Brachythemis contaminata
  • Trithemis pallipinervis
  • Macrodiplax cora
  • Tramea transmarina



  • This morning we went along Neo Teo, around Sungei Buloh, originally for cycling, but in the end the bike rental shop wasn't open, so we walked instead.
    Well, here's a picture of what the pond looked like:

    Trithemis pallipinervis is different from the other, more commonly seen, Trithemis species in a rather obvious way when you see it perched. T. aurora is also known as Dawn Dropwing, T. festiva as Indigo Dropwing, the name coming from the fact that their wings droop when they are at rest. However, T. pallipinervis rests with wings raised above, as if as a mirror image of the other two T. sp. more commonly seen in Singapore.
    Tramea transmarina is also a migratory dragonfly, like Pantala flavescens.
    Macrodiplax cora has very sparse wing venations, with a long black stripe down its abdomen.

    Apart from the various dragonflies, we also saw some birds, including the Slaty Breasted Rail. I also heard the Purple Swamp Hen, while my dad and brother saw it fly (how lucky xD)

    In the afternoon we also went to Sentosa, so on an entirely unrelated note, here's a photo of a Nudibranch (possibly) that we saw:

    Dairy Farm

    Location:
    Dairy Farm
    Species seen:
    Anisoptera--Dragonflies
    Gomphidae
  • Paragomphus capricornis


  • Whoa, long time since I last posted... But this one is a beauty(:
    Paragomphus capricornis is a rather rare species in Singapore since we don't really have many sandy banks which the larvae need to emerge.
    But we seem to have found a breeding spot, because we spotted both the female and the male today:

    The first picture is of the female and the second of the male. The difference is the tip of the abdomen, because the male has a hook downwards while the female doesn't. You can also see the sexual organs of the male if you look at it sideways, it is approximately where the thorax ends and the abdomen begins. (:
    Also spotted some other species today, and we will probably go for a trip up to Kota Tinggi for more odonata next week ^^
