This is an experiment in marking a photo with an arrow. Useful in inndicating specific setae. It is the lower katepisternal seta on a photo of Lasiomma cf seminitidum Zett.

I don't know if the arrow will transmit.

:)

You can confirm that in Overviews section there are some photos with many arrows. :)
Please, take a look on them:

and

and

but please continue to do that so other people can understand what we are talking. :)

Michael: Houston, we have an arrow. Your version is OK, but it has ragged edges - I guess it's a smaller bitmap arrow scaled up to required size.

Jorge: "other people can understand what we are talking" - good luck with that :)

KAHIS: :D

Are we normal? :D

"Houston, we have a problem. We are seeing strange things here in space, we are seeing some guys running happily and trying catch a bunch of flies!!! Can you explain this rather strange and disturbing activity?" :| B) :D

I just looked up your links, Jorge. Great stuff! Tell us how you get these enlarged photos please.
My experiment was to see if I could add an arrow to your photo (Should have mentioned this), by copying to another programme on my computer which has this facility; then send it to the forum.
One point: the term first flagellomere has been deemed incorrect by Stuckenberg (South Africa) and should be now called postpedicel

Thanks.

At first I must say that the photos in Overviews are not mine, except the wing venation for Trichocera.

The photos I took like this Lasioma are really mine.

In my case I use a canon 30D with Sigma 105 mm lens and Kenko extension tubes. Sometimes I add a 50 mm objective so I can gain more ampliation. Now i use another lens, the mpe.
