<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Surely most invasive species have colonised because of humans,
whether deliberate or not, so the distinction does not seem to be a useful one.
The key point is that most colonisations fail, however they occur in the forst
place: it is the successful ones that become 'invasives' and the reasons for
that success are interesting and worth studying.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>I would like to continue with
the discussion on introduced species, and if some of them may be considered
'invasive'.<o:p></o:p></p>
</div>
<p class=MsoNormal style='margin-bottom:12.0pt'>In the webpage <a
href="http://invasive.org">invasive.org</a>, dealing with invasive species for
USA, there is a list of syrphids: <a
href="http://www.invasive.org/browse/TaxImages.cfm?fam=475">http://www.invasive.org/browse/TaxImages.cfm?fam=475</a><o:p></o:p></p>
</div>
<p class=MsoNormal style='margin-bottom:12.0pt'>I have a special interest in <i>Simosyrphus
grandicornis</i>, which has been introduced to a number of Polynesian Islands
and Hawaii. So, if this species has been introduced by humans, why now consider
it as invasive? <o:p></o:p></p>
</div>
<p class=MsoNormal style='margin-bottom:12.0pt'>Does anyone have more
information about the introduction of <i>S. grandicornis</i> or its
invasiveness?<o:p></o:p></p>
</div>
<p class=MsoNormal style='margin-bottom:12.0pt'>Thanks for the helpful
comments.<o:p></o:p></p>
