More about the biology of a parasitoid mite

Following Monday’s blog post, we continue to explore the life of  Macrodinychus mites that parasitize an invasive ant species in Mexico, the Longhorn crazy ant. Today Dr. Hans Klompen shares some of the details of the mite’s life cycle that he has discovered with us.

Here is an image of two Macrodinychus larvae that were found attached to an ant pupa. We had to magnify the ant 400 times to make the mites visible. The larvae are tiny, even in mite-standards, while the adults are large, 1 mm or more in length.

What do the larvae and nymphs look like?


Tell us a little bit more about the biology of these mites, e.g. how does the female give birth to young?


How do the mites disperse to new hosts?


Why is this research important?


What do you think?  Can/should these mites be used to control invasive ant species?
We would like to hear from you – please leave a comment.

  1. Hi there,

    I’m struggling with a bad mite outbreak everywhere in my house, on my pets and me. I think it may be this mite.
    Is there any possibility I could send you photos to determine if it is this mite? Debbie
