Description:

This was just one of half a dozen pairs laying in the same area. The puddles will probably dry up, but perhaps not until the late spring - they hang around. What's the prognosis for the young?

Prognosis for young...

In all likelihood the chance of eggs laid in temporary puddles producing adult dragonflies next year is probably very slim in most cases.
The earliest that darters tend to emerge in the UK is around late May, with most not emerging until late June or July, and it is perhaps likely that the earliest individuals come from eggs laid much earlier in the previous season than late September.
Shallow, warm water can promote faster growth though, if there is enough food available (and if enough eggs hatch in the puddle there will be food available for a few of the strongest larvae!).

I'd Better Keep an Eye on that Puddle

We'll see what happens over the next seven or eight months.
