  1. Lovely tiny Collembola! I discovered that I have some inhabiting my terrace and that show up in the coldest of the winter sometimes :-) Posted one year ago
    1. Hi Pato ... pssst ... these are not Collembola (Springtails) but Psocoptera (Barklice) ... but I won't tell ;o)

      1. Haha8 they are cute anyway :-D Posted one year ago
  2. Totally cute! Posted one year ago
  3. Great photo's. Some time a go I saw one of these on the toilet sink. So small I couldn't see it was an insect at all, it was just a moving dust spec. Only on the picture I saw what it was (I can't find the picture now :(
    I am a bit jealous on these photo's. Even with 2:1 magnification I couldn't get this amount of detail.
