Lonchopteridae?

Evening,

I originally thought this specimen was a Woodlouse but it turns out I am wrong stupidly enough. The kind folk on the Wild About Britain forum put me in the right direction and it looks pretty much like a [i]Lonchopteridae[i/] species.

It was found on oak leaf litter at Yarner Wood near Bovey Tracey in Devon on Saturday (12/02/2011). It measures roughly 3-4mm in length at the most not including the long thin antennae and 'rear antennae'. It is very lethargic and does not move quickly.

Is anyone able to push this to a species identification or is [i]Lonchopteridae[i/] the furthest it can be taken?

Regards,
Andrew.

Re: Lonchopteridae?

It is Lonchoptera, but I don't think it's possible to go any further.  Some fanniids and platypezids also have flattened tortoise-like larvae with frills but only Lonchoptera has the long processes fore and aft.  I described L. nigrociliata (Dipterists Digest 3, 28-31) and there are a number of illustrations of possibly L. lutea or L. bifurcata, but there are another four still to rear.  Lonchoptera tristis is the most likely candidate in leaf litter within a woodland, which is the habitat of this species (and I've had adult tristis from Yarner Wood).  I usually find the two common species (lutea, bifurcata) at the base of grasses.

Re: Lonchopteridae?

Evening Martin,

Thanks for chipping in with advice on this specimen. It is a pity it can not be taken to species conclusively but your words now give me an idea of looking out for adult L. tristis in Yarner Wood from now on.

Regards,
Andrew.

Hi Andrew

Is there any chance this could be reared through to Adult? From memory, I don't think Lonchoptera tristis has been described that well?

Martin is correct about Lonchoptera tristis is the most likely candidate in leaf litter. my experience is adults are most abundant in the autumn, and mostly on beech. I would be interested if others experience is the same or not?

I have the pupa of Lonchoptera nitidifrons to finish writing up. That specimen was also found in leaf litter.

Evening Mark,

Sadly, I do not have the specimen any longer. I shall make a note of revisiting Yarner in the autumn as I usually not bother after early summer.

Regards,
Andrew.

Re: Lonchopteridae?

On the subject of Lonchopteridae, in Kenneth Smith's H.I.B.I. Handbook he states that Lonchoptera bifurcata (L. furcata) males are rare. Having recently taken a male in the west of Northamptonshire I wonder if this is still regarded as being the case (the handbook was written over 40 years ago!)
