Looking for help identifying a tree, and methods to control sap (if possible)
Good day.
I have a tree in the front yard of my recently purchased house, and I was wondering if a kind arborist out there could identify the tree, and if possible tell me if there's any way to control the sap (or to make it less tasty), or alternately when yearly I should expect this sap. I don't mind the sticky residue covering the lane and cars, but the many bees it draws is a bit of a concern. I've put several pictures at http://www.yafla.com/~dforbes/tree/index.htm. Thank you for reading. Have a great day. |

While I don't know what kind of tree you have or why the bees and such like
it so well, the picture of the critter on your web site looks like some kind of hornet. You really really do not want to get stung by a hornet. One stung my mom several years ago and we had to take her to the emergency room, and she is not allergic to bees, etc. Shell "Dennis Forbes" wrote in message m... Good day.

It is not the tree itself which exudes sugary solution, but the aphids. As problems go this is a very well known one. PvR |

Thank you for reading. Have a great day. It's a Lime, a species of Tilia. There is an American species [1], and Bee-tree is used as a vernacular name for at least one variety of this. However I think this is the European Small-leaved Lime (Littleleaf Linden in American vernacular) Tilia cordata. The flower bracts of Limes, as shown in the first picture, are unmistakable. In most species the flowers are pendant, but in Tilia cordata, and allied East Asian species, the flowers are borne at all sorts of angles. In Tilia cordata the underside of the leaves usually has a blueish cast. For my details on identification refer to my web page - see sig. The leaves of many poplars are superficially similar to those of limes; however poplars usually have no more than 3 veins meeting at the base of the leaf, and limes have 5 or more. The habit of the trees also differs. The flowers of lime produce copious nectar, which attracts bees. The sap that you refer to however is honeydew, the excreta of aphids. The sap can occur at any time during the growing season, but tends to be later in the year when aphid populations has built up. Google for Tilia aphid control for possibilities for control. Limes are too big for techniques useable on perennials to work, but if it's not too big, mechanically dislodging the aphids with a water hose might reduce infestations. [1] At one point many species (30?) of American limes were recognised, but these have been reduced to one, very variable species. -- Stewart Robert Hinsley http://www.meden.demon.co.uk/Malvace...a/Britain.html |

They also knew about research into the alleged toxicity of Tilia-honey (clearing the tree), but added a hypothesis, namely that there was a discrepancy between the production of honey and the spreading of an attractive smell. They felt that Tilia still smelt strongly while honey production was dropping off, luring in bees that it could not feed. PvR |

Thank you for reading. Have a great day. Thank you for posting the answer on your page. I don't know about the tree, but I think you have the insect mis-identified. Look at the pictures of a Yellow Jacket & a Bald Faced Hornet beside each other at http://www.borealforest.org/insects/insects15.htm Close-- but the Yellow jacket has Yellow stripes, and they begin his abdomen. Your insect is a Bald Faced Hornet. [still likely there for the same purpose- eating insects] When the leaves drop you'll probably see a large paper nest. Wait until a couple hard frosts & you can bring the empty nest inside as a souvenir. I went googling for a picture of the nest and found this page; http://www.unexco.com/gallery/hornets.html which says that hornet "is actually a large yellow jacket and not a true hornet". It's been a long time since I studied entymology, so I might stand corrected on that count. Jim |

As to your insect problem... you probably have more than one insect you are dealing with. The problem is PROBABLY not sap, but honeydew, which is sap that has been exuded by aphids. Your tree MAY have an aphid infestation, which is causing the rain of droplets. Are there a lot of ants going up the tree, too? They are often found taking advantage of the honeydew exuded by the aphids. As to how to control... you should consult with a professional ... I have heard of people spraying affected trees with pesticides to control the aphids, but this can be very difficult to be effective with tall trees. |

The white faced hornet that makes the large paper ball is technically
a yellow jacket. Hornets are old world insects. |
