Amatoxins, the class of toxins found in these mushrooms, are thermostable: they resist changes due to heat, so their toxic effects are not reduced by cooking. Amanita phalloides is the most poisonous of all known mushrooms. [6] [7] [8] It is estimated that as little as half a mushroom contains enough toxin to kill an adult human. [9]
To attract mates, the adult insects create a tapping or ticking sound that can sometimes be heard in the rafters of old buildings on summer nights.

The cycle begins with an infective juvenile, whose only function is to seek out and infect new hosts. When a host has been located, the nematodes penetrate into the insect body cavity, usually via natural body openings (mouth, anus, spiracles) or areas of thin cuticle. (Shapiro-Ilan, David I., and Randy Gaugler. "Nematodes.")
