Re: need help about dragonfly larvae

[quote=macro junkie;474304]the comment on will u be there to see it hatch in the jar..well i dont work..im at home all day every day so yes i will/QUOTE]
I still don't believe that you can watch it all the time, and I'd be a little put out if after a few weeks of feeding and intensive observation I only noticed the emergence when it was half over! - be prepared for some early mornings!

No problems there then, and as you say it will fly off when it is ready (usually well before they have fully hardened).

This depends on the species that you catch. The larvae of some species only live in flowing water because this tends to have a higher oxygen content. However, if you go dipping in stagnant ponds when you try to find your subject you will catch something that can tolerate less oxygenated water (Southern Hawker for example). I can't see how an air pump would do any harm though so if you have one handy in can't hurt to use it.


Good luck!
