Counting spots

I love the bright pops of colour ladybirds (or ladybugs, as they’re known in some countries) provide on the leaves of trees, shrubs and grasses as I’m meandering through the landscape. And they’re usually easy to identify, simply by counting their spots, which is always a bonus with insects. These are a few I’ve recently encountered: 14-spot (Propylea quattuordecimpunctata) and 22-spot (Psyllobora vigintiduopunctata); a new species for me, the 24-spot ladybird (Subcoccinella vigintiquattuorpunctata) (recognisable by its red head, even if you can’t count the spots); and two that are named for their colours so no spot counting required, the Cream-spot (Calvia quattuordecimguttata) (okay, this could be confusing as it has 14 spots and isn’t really cream, more of a red-brown) and the Orange ladybird (Halyzia sedecimguttata).

It’s a miracle!

I believe I may have an addiction to ladybirds! When I decided to write this post, I thought I’d just check that I hadn’t covered this topic already: of course, I knew I had written about ladybirds before but I didn’t realise quite how many times. There’s a post here and here and again here and another one here. Well, in spite of all those, here’s another one because, when I found all the Orange ladybirds pictured here within five minutes of each other yesterday, I was struck yet again by just how incredible is their transformation from egg to larva …

When I’m out and about on my wanders, it’s usually a preponderance of Harlequin ladybirds that I see but this day was different. Instead of Harlequins, there seemed to be beautiful little Orange ladybirds (Halyzia 16-guttata) wherever I looked. And there weren’t just adult ladybirds – almost every leaf I turned over had their larvae as well. And this was across two different parks, not just in one location.

We are constantly warned that the invasive Harlequins, first recorded in Britain in October 2004, are a serious threat to Britain’s native ladybirds, and surveys have shown that most native ladybirds are in serious decline, partly due to the Harlequin but also due to habitat loss. Perhaps the Orange ladybird is fighting back. It has apparently adapted to living on different tree species, first the sycamore and more recently the ash, so this may be aiding its apparent increase in abundance. I certainly hope so!

Don’t forget that we can’t know what’s happening with British ladybirds (or, indeed, any other living species) unless sightings are recorded. You can record yours through your local biodiversity records centre or directly with the UK Ladybird Survey website here.

There’s a cannibal in my kitchen

For the third time in as many weeks a Harlequin ladybird (Harmonia axyridis) has appeared as if from nowhere in my kitchen. They like to find somewhere cosy to hibernate the winter away so I’m sure a warm spot near my gas boiler would suit them very well and normally I wouldn’t mind but this is the most invasive ladybird on earth.

The voracious little Harlequin originated in Asia but was introduced firstly to North America and later to Europe to control aphids. Though it only arrived in Britain in 2004 – perhaps blown across the Channel, or it may have hitched a ride on a vehicle – it has already spread throughout half these isles. The problem is that the Harlequin doesn’t just eat aphids; not only does it compete with native ladybirds for food but it also devours their eggs and larvae, as well as the eggs and caterpillars of butterflies and moths. It may look cute but it has the devastating potential to wipe out all 26 resident species of ladybird.

This is one time when I really wish this ladybird would fly away home!
