“Sappreeders: ’. 
Members of this family can be found in quantities, whereever 
sap exudes from trees, early in the spring. This is particularly 
the case with maple trees. I have trapped hundreds by laying 
chips on top of a freshly cut maple stump, where the sap was 
exuding. Under these chips were congregated 20 species and 
hundreds of individuals. A mixture of vinegar or sour beer, and 
brown sugar or molasses, will also attract them, if spread on a 
log in the woods, and covered with chips.
