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.

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.

The tree is a linden (tilia). The "sap" is honeydew from an aphid infestation,
something this tree is vulnerable to. It is this honeydew that attracts the
wasps. To avoid this next year, you should consult an aborist and have the tree
sprayed. It is too large to try doing it yourself.

or buy a batch of lady bugs (AKA lady beetles) and release them to
attack the aphids.

Unfortunately, lady beetles have not proven effective against this insect,
though the lacewings have.

I have seen soft bodied scale insects on basswood trees that have
rained down honeydew. It doesn't happen every year.
In flower you should be able to hear the hum of bees in this tree if
there are hives of bees nearby.

Could it possible be a populus ? I think there is an american populus which
looks like tho one on the picture.

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.

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

This time of year their diet will switch from meats to
sugars. Nothing worse than taking a swig out of a cola
can while outside and realize something has found it's
way inside.

Do you mean in this tree. or in general? I have, in fact, seen lady
beetle larvae sucking the juices from aphids. Perhaps you are saying
they don't do enough damage to make a significant difference?

At any rate, I would think it's worth a try (along with lacewings, or
maybe the lacewings without the lady beetles). My goal was simply to
suggest a non-chemical approach (and less expoensive solution than
spraying a large tree).
