Sweet doings on the Sycamore?

Posted partly out of curiosity. In the local cemetry where I take a lot of my insect species there is a lot of invasive sycamore. One in particular has disfigured leaves with black/dark markings. Today this one was attracting a lot of attention from wasps, hoverflies and flies, who gave every appearance of feeding from the surface of the leaves. I wonder if the damage is causing the secretion of a sweet sap.









Anybody Know?

Comments welcome

Nick

Nice sharp images. The image data says they were taken at 300mm. Did you use a 70-300mm Zuiko, or 150mm Sigma with 2x converter?

Re: Sweet doings on the Sycamore?

Can't answer your question, Nick, but these shots are stunning. They nearly leap off the screen and sting you!

Thanks John

Bit of quick research shows our english Sycamores are maples - maples (like sycamores) are quite qick growing and known for their sugary sap. So my supposition that leaf damage could lead to sugary deposits grows in strength (other sycamores without the damage were not attracting the same attention).

Our group has all sorts of expertise, mayhaps someone will pass along and share their knowledge.

The wasps and others are attracted to the honeydew which is on the leaves. The leaves are punctured by aphids and other insects which feed on the sweet sap (at huge pressure). They move on and the leaves leak the sap (honeydew).

As you say there are a number of trees which can do this. Sycamores and limes are a couple. Which is why you are warned not to park a car under them - you end up with a car covered in small sticky dots. It is water soluble!

A number of our butterflies 'nectar' on honeydew rather than flowers. In good years (dry and warm) you get drunk bees staggering around on the ground under the trees. Which would make a good subject for you.

Nice shots btw.

best wishes

Peter

Interestingly I didn't see any bees - they were harvesting flowers nearby.

Thanks Peter
