Dicyrtoma fusca + Dicyrtomina ornata From this side view, you can see how much larger Dicyrtoma fusca is compared to the others. It&#039;s the &quot;big&quot; dark red springtail crawling over a much smaller one. Opposite and in focus (bright yellow) is a young Dicyrtomina ornata. Look closely and you can see its &quot;spring tail&quot; folded under its body.<br /> <br /> Here&#039;s an index photo for the entire group:<br /> <figure class="photo"><a href="https://www.jungledragon.com/image/104993/dicyrtoma_fusca_dicyrtoma_dorsosignata_dicyrtomina_ornata.html" title="Dicyrtoma fusca + Dicyrtoma dorsosignata + Dicyrtomina ornata"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/2/104993_thumb.jpg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1770854410&Signature=Cid032mlZ8pF4f8R5armivfEjSo%3D" width="200" height="192" alt="Dicyrtoma fusca + Dicyrtoma dorsosignata + Dicyrtomina ornata Here&#039;s the value pack, bulk discount shot of last weekend&#039;s springtail session.

Dicyrtoma fusca + Dicyrtomina ornata

From this side view, you can see how much larger Dicyrtoma fusca is compared to the others. It's the "big" dark red springtail crawling over a much smaller one. Opposite and in focus (bright yellow) is a young Dicyrtomina ornata. Look closely and you can see its "spring tail" folded under its body.

Here's an index photo for the entire group:
