Wolf spider
Référence de la vidéo 11924315
| Wolf spider (Alopecosa sp.) encounters grasshopper (Melanoplus sp.) on log in Ohio. Spiders have poor vision and rely on movement to detect prey. The grasshopper is safe as long as it doesn't move. This one remains motionless, even when touched by spider, not hopping away until the danger has passed. Wolf spiders get their name from the way they run down their prey, like wolves. Most species don't spin webs. They are found throughout the world. | |
