A Visit to Madrona Marsh Preserve

Thursday morning, Kim Moore and I visited Madrona Marsh Preserve in the city of Torrance CA: http://www.friendsofmadronamarsh.com/pdfs/mm-habitat-map-2014-2pgs-web.pdf
We were accompanied by a biologist and an vector insect specialist. We noted all insects observed, and attempted photography, when possible. Here are a few of my digital captures.
I will edit these images with IDs, when available from entomologists and BugGuide.net.
I intentionally darkened these images, because I digitally projected them for a presentation, which tends to wash-out color. I am interested in your opinion, if they appear too dark.

Brilliant set Douglass. Number 12 looks a bit like a Pirate spider egg sac, on the right of it there is, what looks like, the thread from which they hang.

That is a great set Douglass. Very well done. I do not think they are too dark. I like the color, composition and sharpness. You did good my friend.

They don't appear too dark on my monitor.

As a graduate of Kodachrome II, which in my time and place was always shot dark, your pics are perfect! I've always favored darker images with richer colors and higher contrast like these.

I have added an unusual crab spider to second post, now #15. I have also added IDs, mostly courtesy of Kim Moore.

Your #7 is a tachinid fly based on wing veins and antennae and many bristles. I found some somewhat similar tachinids on BugGuide, but not the same. I only go to family level in most cases, which gives general biology info for those who wish. I watched several relatives in Yucatan ranging in front of an army ant foraging pod zooming in on crickets (only!) that jumped to escape the ants, hitting them in the air and laying an egg on them. Some must have been caught by the ants, but others must escape since this was clearly a specialized hunting behavior.These are wonderful photos. Any nibbles on the orange 'fungus of eggsac'? Stumps me, too.

Thanks for the tachinid family classification. I have added it to my description.
