树液经常从麻栎的树干渗出。在这些树液部位经常观察到Carpenterworms（鳞翅目，木蠹蛾科），并认为其参与渗出。2002年至2004年的实地观察表明，20-40%的斑块（树木上的渗出点）庇护着这些昆虫，大约20%的斑块只有它们的巢穴。木工虫丰度的高峰期对应的峰值数量的补丁窝藏他们在所有3年（2002年8月，2003年9月，2004年7月）。有木虫或它们的巢的斑块比没有木虫或它们的巢的斑块有更宽的表面积，渗出更多的树液。此外，它们的实验去除导致渗出量减少，表明这些昆虫促进渗出。这些结果表明，木匠虫有助于通过木材钻孔液渗出，它们的分布和丰富的影响树液资源。
Sap often exudes from the trunks of the oak, Quercus acutissima. Carpenterworms (Lepidoptera, Cossidae) are frequently observed at these sap sites and believed to be involved in exudation. Field observations from 2002 to 2004 showed that 20–40% of all patches (exuding spots on trees) harbored these insects and that roughly 20% of all patches had only their nests. The peak period of carpenterworm abundance corresponded to the peak number of patches harboring them in all 3 years (August 2002, September 2003, and July 2004). Patches with carpenterworms or their nests had a wider surface area and exuded more sap than patches without them or their nests. Moreover, their experimental removal resulted in decreased exudate quantity, indicating that these insects promote exudation. These results suggest that carpenterworms contribute greatly to sap exudation through wood boring and that their distribution and abundance affect sap resources.
