Beauty and the beast

Red vine leaves 

It was a beautiful day in early October (see my post A summer day in October – 7 October 2012), it seemed as if nature was trying to hold onto summer but the signs of impending autumn were all around.  I saw the beautiful autumn colours of this vine and I took a quick picture before I was distracted by a passing butterfly, a beautiful yellow one that enjoyed seeing me chase it from perch to perch without every letting me get close enough for a shot.  I forgot about my lovely vine in the heat of the chase.

It was not until later that I made my connection between the beauty of the vine leaves and a beastie I had managed to photograph earlier.  I was rather contented that I had at last got a photograph.  It is very tiny, just less than one centimetre long, and extremely nimble.  I had caught glimpses of it in the undergrowth during the summer but it had hopped out of sight before I had got a good view of it, much less a photograph!

Stictocephala bisonia

The Latin name reflects the strange bison-like shape of this creature and it was not until I found out its life cycle that I made a connection with my red vine leaves.

Ceresa bubalus or Stictocephala bisonia or cicadelle bubale 

The larvae of Stictocephala bisonia hatch out mid-May to mid-June and feed on herbaceous plants such as dandelions, clover and plantain without causing too much harm to the plants and after five moults become adults.  By mid-July to mid-August the adults are ready to breed and can be found in the vineyards (also in orchards as they are partial to apple trees too) and the females lay their eggs on the young vines on wood between 1-3 years old usually.  The females make a longitudinal slit in the bark and deposit about six eggs each side of the incision.  The eggs are incubated in the safety of the plant until the developed larvae drop to the earth the following year to restart the cycle.

Unlike the herbaceous plants that the adults and larvae feed on, the vines can suffer from their role as nursemaid to the insects’ eggs.  The incisions of the egg laying female and the larvae cause a disruption of the vascular sap bearing system of the vine and result in the spectacular reddening of the leaves.  Heavy and repeated infestation can result in weakening of the vine.  The best treatment is to cut and burn all infected parts.

If I had thought a little more about why a single vine plant should be turning such and unusual colour I would have realised at the time that something was amiss – it was all the fault of that yellow butterfly.

Born in Scotland I have lived in England, Iran, USA and Greece. The house and land was bought twelve years ago in fulfilment of the dream of living in France that my Francophile husband nurtured. We had spent frequent holidays in France touring the more northerly parts and enjoying the food, scenery, architecture and of course gardens. However, we felt that to retire in France and enjoy a more clement climate than we currently had in Aberdeen we would need to find somewhere south of the river Loire but not too south to make returning to visit the UK onerous. The year 2000 saw us buying our house and setting it up to receive us and the family on holidays. The garden was more a field and we were helped by my son to remove the fencing that had separated the previous owners’ goats, sheep and chickens. We did inherit some lovely old trees and decided to plant more fruit trees that would survive and mature with the minimum of care until we took up permanent residence. The move took place in 2006 and the love hate relation with the “garden” started. There was so much to do in the house that there was little energy left for the hard tasks in the garden. It was very much a slow process and a steep learning curve. Expenditures have been kept to a minimum. The majority of the plants have been cuttings and I try to gather seeds wherever I can. The fruit trees have all been bought but we have tender hearts and cannot resist the little unloved shrub at a discount price and take it as a matter of honour to nurse it back to health. This year I have launched my Blog hoping to reach out to other gardeners in other countries. My aim is to make a garden for people to enjoy, providing shady and sunny spots with plants that enjoy living in this area with its limestone based subsoil and low rainfall in a warm summer. Exchanging ideas and exploring mutual problems will enrich my experience trying to form my French garden.

  1. This is an American alien species… alien being very apt here with this appearance… when I found one this year, I didn’t find any info about the vines… but I am now wondering if this creature came in on imported vines?
    Nice post as usual…

  2. That is quite scary, I don’t think I’ve ever seen one, but we don’t have vines or apples so perhaps the garden isn’t attractive to them. Vineyard owners must be terrified because they usually cut back to very old wood so if that is infected they’re going to have to prune almost to below ground level! Christina

    • I’ve no idea how common it is over here. It certainly does seem under control around us. It wasn’t until later that I began to think…autumn red vine leaves?…but the vines don’t turn red in autumn? It was the first time I had ever seen a vine with those colours and we are surrounded by vineyards.

  3. Very interesting post. I particularly like the connection you were able to make between early color change and the culprit for it!

  5. Never seen / heard of one of these! No wonder. Your post made me want to know more about the ‘Buffalo Leafhopper’… Yet another invasive / malign import into Europe (cf Signal Crayfish)… RH

  7. Oh my, I have never seen one of these little critters before. They are impossibly cute, to my eyes at least. I do not have any vines in my garden so am unlikely to encounter them, and anyway perhaps our climate is wrong. You have reminded me, however, that I need to investigate asap why some of the box plants in my front garden are turning brown. As the problem seems to be spreading out from the first plant to die, clearly something is amiss.

  8. That’s a bug I would love to photograph. Then again, I don’t grow grapes.
