Sorry I added my previous comment to the wrong picture. This one is an Aeolothrips female. Apterous form. There are about five species with the basal abdominalsegments yellow.

Hi Tom,
nice gallery with good thrips photos.
This one is not immature. It's a brachypterous female. If you could send samples I will identify the species.
Have a look at my website.www.thysanoptera.com
