An arthropod is an invertebrate animal having an exoskeleton,
a segmented body, and jointed appendages.
Arthropods form the phylum Arthropoda, which includes the insects, arachnids, myriapods, and crustaceans.

        Arthropods are spectacularly successful, with over a million described species (and maybe 5million more to come!), so there is no way I can hope to show even a fraction of Hong Kong's amazing bio-diversity on these pages; for example, I have a 220page book just on the Jumping Spiders of Hong Kong! so I have tried to highlight some of the most common on this site. But for the less common, and more spectacular and interesting, make sure you follow my blog on, or go to the facebook page (in English and Chinese).

      OK, we need a word here about my "classifications".... and this is more "eye-spy fun" than "entomology field guide". I have not gone with the purist (and more scientifically accurate) groupings, but rather tried to sort animals into groups to help with ID. There are plenty of great books out there if you are interested to know more about how these creatures "should" be classified, and many apologies to anyone offended by my more practical approach. However, there should be no errors, so if you find any, please let me know, and I'll buy you beer when we meet.

I have divided this huge of group of Arthropods as follows:
Insects - 3 body regions, 6 legs.

Butterflies - and their caterpillars.

Moths -  and their caterpillars.
Beetles and Bugs


Other - including Ants, Wasps, Bees, Cicadas, Aphids, Mantids, Stick Insects and many others!

Arachnids - 3 body regions, 6 legs.


Plus, I'm a
lso including a select few Crustaceans here (also arthropods) that is Centipedes/Millipedes - multiple body segments, multiple legs.
Whilst for the other Crustaceans that should be here under Arthrpods eg Land crabs, and Crabs etc, please go to Marine/Aquatic.

BUTTERFLIES - and their Caterpillars
And a massive thank-you to Colin Chiu and Jonathan Yang for ID help

   THE DIFFERENCE BETWEEN MOTHS AND BUTTERFLIES:  A very contentious issue....and one which I would defer to Mr. Moth AKA Roger Kendrick for a full explanation. And thank you Jonathan Yang for ID help.  If you see an insect with scaled wings, and baton-shaped antennae, you can be sure its a butterfly.  Meanwhile, click the button below.

oooook, i'm gonna get into all kinds of trouble for this...but hopefully not with my intended audience...See the first image link for an explanation.

 All Demoiselle are Dragonflies but not all Dragonflies are Demoiselle...

Including Ants, Wasps, Bees, Cicadas, Grasshoppers, Aphids, Mantids, Stick Insects and many others!

Arachnids -  2 body regions, 8 legs.
SPIDERS & SCORPIONS, and some CRUSTACEANS -  I'm also including (also arthropods) Centipedes/Millipedes - (multiple body segments, multiple legs).
Whilst for the other Crustaceans that should be here under Arthropods eg Crabs etc, please go to Marine/Aquatic.
