<div>Hi Günter</div>
<div><br></div>
<div>I agree with Martin Speight that your larvae belong to genus
Volucella. Curiously due my teaching activity about urban pests,
sometime ago I found a website with very nice photos about this topic.
Unfortunately (for me) was/is in Swedish or Finnish but the URL remain
in my Bookmark... Apparently the author: Jarmo Holopainen (University
of Kuopio, Finland) show that the larvae of this genus in
relation with Insect Indoor pests. The species that appear in his web
is identified as Volucella pellucens. This is the information that
appear:</div>
<div><br></div>
<div><<Ampiaisvieras (Volucella pellucens) on asumusten
lähellä elävä kookas kukkakärpänen (Syrphidae), joka toukat
loisivat ampiaispesissä. Syksyisin koteloitumaan siirtyvät
suurikokoiset toukat saattaavat tulla sisätilohin.>></div>
<div><br></div>
<div>However I do not use this information in my teach because I
believed that was only accidental (and do not knew exactly what he
said!!) but according you, can be considered as indoor pest, and...
yes according the biology of most of the species of this genus ... I
believe that this people have/had a wasps' nests in the roof or
close... please could you confirm us this point?</div>
<div><br></div>
<div>Graham Rotheray is the best person for the species
identification. He has several papers about Volucella including a key
to the determination of the larvae of North European Volucella
species, please see: http://www.studia-dipt.de/con61.htm</div>
<div><br></div>
<div>The Jarmo's website is: http://www.uku.fi/~holopain/stt/</div>
<div><br></div>
<div>Please look for Volucella in one of the 3 main links of the web
and you can found a very good photos of larvae very very similar your
specimens.</div>
<div><br></div>
<div>Regards</div>

<blockquote type="cite" cite>Hello everybody,<br>

<blockquote type="cite" cite>Yesterday a friend of from the local
museum of natural history <a
href="http://www.inatura.at">www.inatura.at</a> asked me if I could
help him identify a larva which I think is a syrphid. The length of
the larvae is 13mm (without stigmata-"horn" which has
another 1mm of length). The larvae have been found inside houses in
three cities/villages around here (Dornbirn, Feldkirch and Egg, all in
Vorarlberg/Western Austria) during the last week - some in a guestroom
which is not used very often, some in the corner of a room on the
floor with mice's feces around and some "falling from the
ceiling" according to the people who brought the larva to the
inatura.<br>
Could anyone of you help me identify the species or genus? I'd
appreciate any kind of information.<br>
Another thing: What were these maggots doing inside the nearly empty
rooms? (the people here have asked for this kind of information).<br>
<br>
Thanks in advance</blockquote>
