Subject: Crane Fly Emergence on Long Island
A note from Dan Peck, a turf entomologist at the New York State Agricultural
Experiment Station in Geneva, NY alerts us to the fact that invasive
crane flies are emerging on Long Island.
According to a report from the Cornell University Turf Times (CUTT), two species
of exotic crane flies (both of which can be injurious to turf) invaded western
New York in 2004. The European crane fly (Tipula paludosa) and
the marsh crane fly (Tipula oleracea) have both been found western
New York. Apparently adults of the marsh crane fly began to emerge on Long
Island a few days ago.
The following is a direct quote from a "heads up" e-mail I just received from
Dan Peck. Please keep alert, especially in southern New England, for emerging
crane flies. Note that there are several native species of crane flies that
are not directly damaging to turf, so just because you happen to see some crane
flies does not necessarily mean that you will have a problem.
From Dan Peck:
T. oleracea has now been reported from four localities on the
Island over 2006 and 2007: New Hyde Park, Point Lookout, Riverhead
and another site in Suffolk Co. (that Rick Hoebeke pulled from a
bark beetle trap, but whose locality escapes me at present). They
have not yet been detected on golf courses. Nevertheless, in
the greater Rochester area they are more prevalent on golf courses
than home lawns.
Now is therefore a propitious time to scout for this insect. On short-mown
turf (e.g. tees and greens) the pupal exuviae are relatively easy to scout
for as they stick out from the surface like little twigs. If you detect
them, then try and sweep some adults (or blow them from the sky if you have
a pressure washer). Adults will make taxonomic identification much
easier. I would appreciate any samples you could send me directly (exuviae
or insects). Store in alcohol but since this liquid shouldn't be sent
through the mail you should drain it off before you send.
It would be particularly revealing to make collections in areas that intervene
between what we hypothesize to be two separate areas of establishment, western
NY and Long Island. Build community pride by getting your county/state
on the crane fly map!
This is a "collect first, ask questions later" moment. Thanks
for helping us get a handle on how widespread this invasive is and
to help alert the turf industry to their presence.
