Congratulations Mark, this giant of a springtail is our Spotting of the Day:

"Does it make you think of a mini-hedgehog? This Giant Springtail larva (Acanthanura sp.) is our Spotting of the Day! Springtails (Collembola) are small organisms that live in moist environments and are normally less than 6 mm long. The genus Acanthanura, however, has species that can grown to over 10mm".
