I made the most of the weekend sunshine and spent some time in my garden, now with a refurbished pond. Refurbished in that it now actually holds water, it had been reduced to an ephemeral pond at best, an interesting habitat, but perhaps not the most appealing in a garden. On Sunday I decided to use the last of the rainwater stored in the water butt to top up the pond, trusting in the forecast rain to replenish the store. I was almost instantly rewarded with the appearance of a female broad-bodied chaser dragonfly, perching near the pond and then dipping her abdomen into the water as she laid some eggs.
A little later there were two, chasing each other around between bouts of egg-laying and resting up in the sun. I also saw large red damselfly and common blue damselfly in the garden, making three Odonata in the garden before the end of April.
It was a weekend for egg-laying insects I watched, but failed to photograph successfully, an orange-tip laying on the garlic mustard and a holly blue laying on alder buckthorn.
I had not known that holly blue would lay on alder buckthorn, although I did know they used a good deal more species than just the traditional holly and ivy. Laying on my rather small alder buckthorn also puts the caterpillars in direct competition with the brimstone caterpillars when they hatch in a few days after being laid last week.
The early rush of butterflies was dominated by brimstone and peacock especially, with fewer comma and small tortoiseshell. Perhaps because of the very good weather these species seem to have declined rapidly an dare now being replaced by the whites and the first of the arriving red admiral. Small white and green-veined white are residents and typically pick up in numbers during April.
Large white are resident in rather small numbers but bolstered by, sometimes very large, arrivals of migrants.
There is a bit of a race on at the moment to see who can add the next new butterfly species to the UK list. One thing is pretty certain it is going to happen and probably not very long away, in fact it may well already be here. The species is the southern small white, it has expanded from southern Europe over recent years all the way to the channel coast, under 30 miles away. The difficulty is that it is quiet similar to our regular small white, so if you want to make a name for yourself look up the differences, keep your camera handy in the garden and plant candytuft. Why candytuft? Because it is the preferred caterpillar foodplant of the southern small white. It could be you, especially if you live on the south coast, the Isle of Wight has to be a likely location, if someone in Kent does not get in first!
I will end on a picture of the most dramatic plant in my garden, the giant viper’s bugloss Echium pininana which as it starts to flower becomes a tower of bees as the flowers shoot 3 to 4m or more into the air.
I have, of course been recording the species I have seen in the garden and uploading the data to the many citizen science recording schemes, something we can all do for everything from butterflies to earthworms.
There is some Giant Echium near me! I look forward to it starting to flower 😉
I’m off now to look up the southern small white and candytuff, great name!
Thanks for the update and lovely photos.
