Hi Arp, this has been discussed on WAB before about seperate forums for different insects and invertabrates but it was decided for those who are complete novices it would be more confusing than ever, and keep the forum as one for now.
As reguard to the gallery - I know what you mean. But you can use the "search" button and this works really well and just brings up those images with a certain word/words in the title. On WAB it works better as the Latin names "have" to be given with gallery submissions unless it is going into the unidentified or forum image catagory. Here we don't have that option or moderated galleries so there are images with no positive ID, Latin, English names or both. This can be an advantaged as it sets off discussions in the gallery.
If everyone can give as much info as possible with their uploads it so helpful to others. I know I have recently uploaded to the insects with a title of "bee and Fly" because I have no idea what they are, and any help will be appreciated. People should still be able to upload and share their images with no info, without feeling they don't know enough which may even deter them from joining in. The best thing we can all do is give positive help and ID where we can to encourage people - the more the merrier.
I hope this won't put you off searching the galleries, and contributing here, try the search button. I am sure you will have so much to offer with your interest in insects
