It was great to go out for a nature walk today — I’ve been too busy recently. It was only in my local area and just for a couple of hours. The highlight was finding a new (to me) species of longhorn beetle. It’s a small species (5mm) so I was pretty lucky to spot this pair on a branch in the forest.

I often see these big black and white weevils hanging onto leaves like a cross between a koala and a (very small) panda! They walk very deliberately and drop off the leaf when disturbed. I think they are among my favourites.

I think somebody has made a bit of a mistake here! Take a closer look…

It’s remarkable how these Japanese beetles skeletonize leaves — they’re little artists really!!

Such a beautiful weevil… but my photos are very poor. The evening was setting in and I was among trees and the weevil was only 3mm long… If I find one again, I will catch it and take the photo in a well-lit place to show off the metallic gold and green.

Today was Longhorn Beetle day for me! I went out for 4 hours between downpours and walked around my local area to see what I could find. Everywhere I looked I spotted longhorns: 9 species in total. Not bad. Well, just to put that figure into perspective… there are about 800 species of longhorn beetle in Japan!

These are big longhorns (around 30mm) and they were all over the place in the orchards I visited today. I found about 10 and, by the looks of things, they were finding one another pretty easily too !

This tiny jewel beetle was a little devil — running around like crazy and refusing to smile for his photo! Hence the not-quite-in-focus photos. Only about 3mm long but what a beauty.
