Cataloging biodiversity continues despite habitat loss, global mass extinction, and fewer and fewer taxonomists being trained.

60 New Species of Dragonflies Found

And of course, the beetle people just have to one up us.

Parasitoids will end up ruling the word
Yeah, I know, but I think it will turn out that there are more Hymenoptera than any other order. Hardly anyone has studied microscopic parasitoid wasps, but it appears that almost every other species of insect has, at least, one parasitoid preying on eggs and larvae. There are some parasitoid flies also.

This is Trissulcus sp., a parasitoid wasp that was part of a group of stinkbug egg parasitoid wasps that I photographed as part of an insect pest biocontrol project. it is only about 1mm in length. One of the feature that made them interesting photo subjects were rows of small pits on their body that looked like cooling louvers on little robots.

This is a shot I made with an SEM. It is a lateral view of the thorax. You can see the front and hind wing attachments near the top.


These were the stinkbug eggs that I collected the wasp from. You can see that the tops of the eggs have been chewed open by the wasp after it went through the larval stage where it consumed the stinkbug embryo and then went through pupation. If the stinkbugs had survived they top of the egg would be popped open like a hatch.

I don't know the species of stinkbug that laid these eggs, but the study I worked on was looking for the best parasitoid to control Halymorpha haly, the brown marmorated stinkbug, an invasive species from Asia, that is spreading from both the east and west coasts of the U.S.

Absolutely amazing photographs!

Query sp?
https://www.dropbox.com/...g7dicq3l0mj5/Dragonfly-095388.jpg

Care to enlighten me. This was next to a river in Bahia, Brazil.

I really like these beasties. Perhaps not nearly as much as you though .

Re: Query sp?
I am pretty sure this is Orthemis schmidti, a male. Orthemis can be tricky because they are variable and several species look similar. Sometimes O. discolor is mistaken for O. schmidti. Some of my friends are convinced that Orthemis is a ring species complex that stretches through the southern U.S. the Caribbean, tropical S. America, and C. America, basically the neotropics. It is a very complex group and so far, molecular studies have not clarified it.

I am part of a team that is applying for a NSF grant to do a molecular phylogeny for all the Odonata down to the species level. This would be the first large group of organisms to have their complete evolutionary history mapped.

Nice shot!

How cool is this
Things like this is why this is my favorite place on the intertubes. We have world class experts on a number of subjects that regularly post here.

The only thing I have ever been an expert on is photoresist for the decorative sandetching industry, but I have been out of that industry for over 15 years. Oh yeah, the eligibility systems for a major health insurance company, I was an expert in that too. Alas, I find I can not work for corporate america, so no longer an expert at that either.

Thank you all for making me a little smarter
