That is excellent advice, thank you.
I have a reasonably typical digital camera - are my pictures going to be good enough to get species level id's? Or am I forever going to be getting various 'sp' of certain genera?
My hopes are to try and identify as much as possible using this website from when I go pond dipping. |

Some dragon and damselfy nymphs are fairly easy to get to species, providing cetain features can be seen, while some worms/fly larvae can be a job to get to Class let alone family/genus! |

You will find that some distinctive species can be id'd to species while the rest are stuck at genus level if you are lucky. With water-beetles, really the only way to separate all 13 of the Haliplus ruficollis agg. species is to dissect the males. |

| Hence I said 'some' The large red damselfly is pretty distinctive and a good example of the some, and the emperor dragonfly can be identified from the size (ie if its more than 5cm in UK the nymph is probably an emperor) and a top down view of the head looking at the eye shape. Where as seperating the blue damselflies on the other hand can be fun! | | | |
