Answer to the Parasite Case of the Week 649: Non-parasitic insect, a springtail (Collembola). As Blaine mentioned, there is no definitive evidence that it is in the actual specimen. To me, it looks like it was squished on top of the slide - perhaps during cover-slipping, or possibly in the stain/other reagents. If this was my case, I wouldn't include it in the final report since that would just cause confusion for the ordering provider and patient. I'd just admire it and show it to my trainees 😊. The iridescent colors are beautiful!
