Four-Spotted Sap Beetle ~ Glischrochilus quadrisignatus

Four-Spotted Sap Beetle (or ‘picnic beetles’, ‘picnic bugs’, or ‘beer bugs’) feed on sap from injured trees, decaying vegetables or fungal matter. They love ripened fruit, as well as beer, wine, fruit juice and fermented beverages. The beetles like to party in large numbers when these beverages are present, often drowning while enjoying their libation. Then I get to enjoy protein in my wine =-P

They can be a nuisance to farmers, however they don’t generally bother crops until something else causes the crop to be damaged in some way. Once damage is done, like Japanese beetles nibbling on tomatoes do they come from miles around. They aren’t strong fliers, however scientists have tested marked beetles by placing a basket of rotten tomatoes 200 yards away, and the beetles found the prize in less than two hours.

Researchers have also found that their favorite food is beer mixed with bananas. Hmmm, I do peanut butter and bananas.. However, I wouldn’t think to down my meal with beer, yuk.
