Earth fleas, commonly known as springtails, belong to the order Collembola. They are tiny, wingless arthropods, typically 1–3 mm long, with a furcula—a spring‑like tail appendage that enables rapid jumping. Their bodies are soft, covered by a cuticle that may be smooth or granulated, and many species possess a ventral tube (collophore) used for moisture regulation.

What symptoms manifest after a tick bite and when does the disease appear?

Views: 1. Date latest changes: .

Redness and swelling commonly develop at the site where a tick attaches.

Swelling accompanies the erythema, often resulting in a raised, tender area around the attachment point.

Where do pubic lice appear, and what are typical sources of infection?

Views: 1. Date latest changes: .
