Longbodied Cellar Spider Pholcus phalangioides
Family Pholcidae (Cellar Spiders)
Size Female: 7-8mm; Male: 6mm
Habitat: fields, meadows, woods, tall grass, shrubs, and bushes, houses
Active hunters, they travel over vegetation looking for small insects to catch.
One of three completely different arthropods nicknamed daddy-long-legs: Cellar door spiders (true spiders), Crane Flies (insects) and harvestmen (arachnids but not spiders).
All three are subject of a wide-spread urban myth that says daddy-long-legs are the most poisonous animal in the world, but are not dangerous because their mouth is too small to bite humans. Check out the video below where Mythbusters disproves this myth.
