Videos 1 and 2. A. oligospora capture. With A. oligospora, a nematode is captured by adhesion, not only when it enters a trap (Video 1) but also when it merely touches the outside of a trap (Video 2).

Video 3. A. oligospora penetration. Within an hour after contact, the fungus breaks through the nematode cuticle with a thin hypha which swells to become an infection bulb. Cell components from the trap flow into the infection bulb.

Video 4. A. oligospora digestion. Trophic hyphae grow out of the infection bulb, finally filling the nematode body. Digestion of the nematode occurs within 1 to 2 days. New traps develop outside the body.
