Eulophid Wasp Pupae - Family Eulophidae Here&#039;s what I think is going on here...The tiny (~1-2 mm) black blobs are the pupae of Eulophid wasps. They are found, attached to leaves, in an upside down position. As larvae, the wasps feed on another insect larva (such as a lepidopteran caterpillar or leaf beetle larva). When mature, the wasps emerge and pupate on the leaf. I think the host(s) was possibly a leaf beetle larva(e) because of the way in which the leaf was defoliated, and there were leaf beetle larvae on these leaves. Of course, I could be wrong about this entire scenario.<br /> <br /> Habitat: On alder (Alnus sp.); bog<br /> <br /> <figure class="photo"><a href="https://www.jungledragon.com/image/107251/eulophid_wasp_pupae_-_family_eulophidae.html" title="Eulophid Wasp Pupae - Family Eulophidae"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/3232/107251_thumb.jpg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1759968010&Signature=bJHhbFjepJ89F1vZoFBt0VWgzq0%3D" width="200" height="138" alt="Eulophid Wasp Pupae - Family Eulophidae Here&#039;s what I think is going on here...The tiny (~1-2 mm) black blobs are the pupae of Eulophid wasps.

    I've noticed similar and thought they were droppings. Thanks for the info and insight. This world is an amazing place.
    How do you get two photos up at once.

      Within a comment or a description field, you can paste the address (URL) of any JungleDragon photo, and after saving the comment it will render that links as a thumbnail. This is also the way to include videos from Youtube, just paste the link. Hope this helps? Posted 4 years ago
