[Syrphidae] Syrphids as invasive species

[ximo mengual sanchis]

Dear all,

I would like to continue with the discussion on introduced species, and if
some of them may be considered 'invasive'.

In the webpage invasive.org, dealing with invasive species for USA, there
is a list of syrphids: http://www.invasive.org/browse/TaxImages.cfm?fam=475

I have a special interest in *Simosyrphus grandicornis*, 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?

Does anyone have more information about the introduction of *S.
grandicornis* or its invasiveness?

Thanks for the helpful comments.

Best wishes,

Ximo
