Is the lined orbweaver poisonous or venomous?

Not in any medically significant way. Like almost all spiders the lined orbweaver (family Araneidae) has venom for its prey, but it is not a widow or recluse, the two U.S. groups whose bites need medical attention.

About these numbers

A species is listed for a state once GBIF holds at least 10 records of it located inside the state by coordinates, under any license. Every count, share, month and county shown is computed only from records published under CC0 or CC BY, so a listed species can show few or no counted records. Monthly patterns show when people record spiders, which also reflects when people are outdoors. Venomous status follows taxonomy: pit vipers and coral snakes; widow and recluse spiders; the Arizona bark scorpion. Records filed under older names count for the species they belong to today.
