Tree Following: June 2015

I am following a tree this year – a Field Maple to be precise – along with Lucy at Loose and Leafy, and many others around the world. This month my tree is looking lush and leafy. 🙂

However, on closer examination there are very few seeds that have remained on the tree, most dropping at or just after flowering stage… and a lot of aphids earlier this month have made an ugly mess of many leaves too… Maybe it became susceptible due to stress caused by our very dry April?

But wait, what’s this? A strange orange and black bug…

And another one… chomping away!

I have identified them as the larva and pupa stages of the Asian Ladybird Harmonia axyridis, also known as the Harlequin Ladybird, the most invasive ladybird on earth!

It has the potential to threaten our native ones, eating both their food sources and their larvae. So I will be on the lookout for the adult now, to see if I can differentiate between it and our native ones. Not that I can do anything about it, but I’ll keep you posted anyway. A good website to help with identification of ladybirds, at least in western Europe, is the Ladybird Survey site, which has information on the Harlequin too. Here is a link to some Wikimedia photos of the adult Harlequin Ladybird.

Have you seen this ladybird? Do you see other ladybirds too, or did you in the past?

 Thanks go to Lucy for hosting this meme… I probably would not have learned that we have this ladybird in our garden if I hadn’t been watching my tree so closely!
