The past two weeks of unprecedented September heatwave since my previous Wandering Naturalist event have continued to prove one thing: we have changed our climate and will continue to do so unless we turn things around very quickly. Climate change (or as we should be thinking, climate collapse) is made up of shorter-term weather effects and the recent heat has certainly brought the season to a close for many plants in the garden. Likewise, the diversity of insect types is declining, although the numbers of Honeybees, bumble-bees and carder-bees in particular is still rising, presumably as their nests continue to grow. Hornets too, but not generally visiting the flowers themselves: they are working their way around the flowers trying to catch insects which they kill with a sting and take back to their nests to feed to their developing grubs.
The daisy family is really taking over as the main provider of nectar and pollen resources to the bees and a whole host of other insects, and will remain so now until the first frosts:
And a major addition in the Reservoir Garden since the last walk has been the opening of Phacelia flowers, now literally buzzing with life! A great species this to improve the wildlife-friendliness of any garden, they will self-seed merrily into any gaps.
Of course bees and the like are not the only creatures we want to encourage. Lots of others make up the garden food-web, as pollinators, predators, parasites, decayers, food for others and generally providing the services needed to turn a garden into an ecosystem. Just a few examples are ladybirds, flesh-flies, parasite-flies and harvestmen:
Some dragonflies and damselflies also go on well into the autumn, though most of the summer species have now expired. Those we are likely to see for some time yet are Ruddy Darters and Willow Emeralds (both of which we saw mating), with a few Common Darters and Migrant Hawkers that didn’t hang around to be photographed.
And so to the butterflies and moths: during the two hours, good numbers of at least seven butterfly species were seen, taking advantage especially of Buddleia and Verbena.
Notable was a brand-new generation of Green-veined Whites, along with two species of renowned migrant to our shores, at this stage of the year as likely to be progeny of spring immigrants rather than new arrivals: Painted Lady butterfly and a couple of Hummingbird Hawk-moths, always a delight to watch working their favoured flowers (today, Buddleia):
And all of the above set to a constant twittering background of migrating Swallows overhead, no doubt catching some of our insects to fuel their trans-equatorial flights to come, plus the squeaks of Meadow Pipits and Siskins, birds just arriving here from the far north-east to take up their winter haunts.
So summer may be over but the garden goes on, and will continue to do so until the weather turns much cooler; there are still plenty of flowers still to come and feed our creatures!
If anyone would like to join me in the garden looking at its wildlife, I am planning on repeating this walk (weather permitting) for the last time this year on 29th September, between 1100 and 1300. No need to book, just come to the garden (normal entry price – see our website for details) and ask at the Visitor Information Centre where I will be and when, and come along and find me! Nearer the time, if the weather is looking at all dodgy, please feel to contact me using the Contact tab above to check it is likely to be running.
