Livings With Sap Beetles

Sap Beetle

Sap Beetle

Sap Beetles in the genus, Glischrochilus, overwinter as adults and are commmonly seen in spring feeding from sap oozing from trees. In fall they can be attracted to harvested fruits and cause damage. Foott and Timmons* reared the sap beetle, Glischrochilus quadrisignatus in captivity. Major findings: Beetles died in 48 hours without an external source of water. A single female could produce over 200 eggs. The beetles developed rapidly on ears of corn buried in the sand. The high fecundity of females and overwintering may explain why populations are large in fall and small in the spring.
