mites?
Hello Bugman,
I just came over your site on the internet. I like taking macro shots of insect and today I have taken an interesting one. There are were some red dots on the wing of a dragonfly. I think maybe they can be some sort of insects or mites. I live in Hungary, Europe I hope you can help me anyway…
Best regards.

Dear Ambruzs Péter,
Your photo is beautiful. We suspect you have photographed the Locust Mite, Eutrombidium rostratum. Essig writes that it : “is the common locust mite of the United States and Europe. It is a large bright red species. … They are often taken on the body and wings of grasshoppers, crickets, katydids, and mantids, and do not attack humans.” Even if it is not that exact species, you have most definitely photographed mites hitching a ride on your dragonfly.

Locust mites on dragonfly (8/7/04). You’re close here. These mites are related to trombidiids, erythraeids and chiggers, but are actually larval water mites in the family Arrenuridae, genus Arrenurus. Water mites have the same life cycle as their terrestrial relatives (i.e. parasitic larva, predatory post-larvae), but the predatory stages are fully aquatic, living in ponds, lakes and streams. Arrenurus species commonly parasitize odonates. Unlike the red larvae, the post-larvae are a beautiful greenish blue, and are good swimmers in ponds & lakes.
