Our new pond only went in just over 5 months ago, but it’s been truly amazing what has already found its way here. One of the groups of animals we’d really hoped to attract was the Odonata – the dragonflies and damselflies. Of course we didn’t expect to get them for a few months, they don’t start emerging until the warmer weather comes, so all we could do was watch and wait. One good thing about the lockdown – it gives you plenty of time to watch and wait by a pond.
Right on time though at the end of April our first species arrived – the Large Red Damselfly. I’d spotted one down at the allotments, so was keeping an especially beady eye out and the next day one found its way to our pond.
Within a few days I was even more excited to find we had a pair of mating Large Red Damselflies. The male is the upper one of the pair. He has a pair of hooks at the end of his abdomen which he uses to hold onto the female around her neck. He holds onto her while she lays the eggs to prevent other males getting a look in!
Their larvae take two years to develop, so all being well, we should have our own “home-grown” red damselflies emerging from the pond in 2022.
I was barely getting over the excitement of the first damselfly’s appearance when the next one turned up – a stunning blue, or as it turned out Azure Damselfly. Since then we’ve seen them a few times, both males and females, but have never spotted a mating pair. Hopefully they have perhaps just been more discrete than the red damselflies and we will be lucky enough to have some emerge next year – they have just a one year life cycle compared to the 2 year for the reds.
The next two photos are of female Azures, below which are 2 males. The females have a bluey green tint, while the males are a much more vivid blue – azure I suppose!
As the pond was new and dragonflies and damselflies take at least a year to develop, we hadn’t expected to get any newly emerging ones. What we hadn’t banked on was getting damselfly larvae arriving with plants we’d ordered. This is the only explanation I can think of, for finding a newly emerged damselfly still pumping up its body on a reed.
The exuvia that the new adult had crawled out of was still clinging to the bottom of the reed, like some weird little alien.
The damselfly was very pale; it can apparently take a few days for them to develop their mature colouration, so we can’t be sure what species this is, but it’s probably one of the blue tailed ones. To start with the abdomen was shorter than the wings, but as we watched, it pumped itself up until eventually the abdomen was clearly much longer than the wings. You can see this in the sequence of photos below.
While its rear end was busy getting bigger, it had a quick wash and brush up round the head using its front legs.
Despite us both sitting there watching, we somehow managed to miss the moment of take-off. But a few minutes later we spotted this one just a foot away on a plant by the pond – probably/possibly the same individual having a rest after all the exertions of emerging. It has darkened up, but still lacks the blue colouration.
So that’s a round up of our damsels – very pleased to have such success with the pond in only the first few months. I’ll do a second blog post for our dragons next – the damsels have been great, but the dragons really are stunning!
