COASTAL FLOOD WATCH: Issued when there is a potential for at least moderate tidal flooding in the next one to two days. The chance for moderate, major, or record flooding levels triggers a coastal flood watch.
The false blister beetles, cardinal beetles, and soldier beetles also produce cantharidin. It is a poisonous blistering agent and can cause severe chemical burns. However, these same properties make it effective as a topical medication.
A few beetles or as many as 200 beetles have been reported as a lethal dose. Doses of cantharidin used to experimentally cause death in horses range from 0.45 to 1 mg per kg (2.2 lb) of body weight. The highest reported cantharidin contentâof the striped blister beetleâis 5.4% of the beetleâs dry weight.
