Northern root-knot nematode (Meloidogyne hapla) is a vegetable pathogen which produces tiny galls (a sore caused by friction and abrasion) on around 550 crop and weed species. They invade root tissue after birth. Females are able to lay up to 1,000 eggs at a time in a large egg mass. By surviving harsh winters, they can survive in cold climates. (Hence, the name, Northern)

“‘What is the world, O soldiers?
It is I,
I, this incessant snow,
This northern sky;”
