枯木是真菌和昆虫的重要栖息地，这两个巨大的不同群体对森林生物多样性做出了贡献。与无数关于真菌-昆虫关系的研究不同，子囊菌孢子囊上的昆虫群落很少被探索，特别是那些隐藏在树皮下面的栖息地。在这里，我提出了我的观察昆虫群落动态Biscogniauxia sp.在橡树死木材上从早期变形阶段到成熟的远变形阶段，借助于松鼠可能针对这些真菌的脱树皮行为。3 - 11月，共观察到38个昆虫类群。此外，Librodor (Glischrochilus) ipsoides、Laemophloeus submonilis和Neuroctenus castaneus在异形到远形的过程中与Biscogniauxia spp有着密切的联系，且群落组成与Biscogniauxia spp的存在与否存在显著相关。下蒙氏乳杆菌与变形和远变形阶段均呈正相关。与异形期呈正相关，与异形期不相关。castaneus于6月至11月在Biscogniauxia种上繁殖。这些结果表明，这些昆虫类群的孢子囊在不同的发育阶段具有重要意义。
Dead wood is an important habitat for both fungi and insects, two enormously diverse groups that contribute to forest biodiversity. Unlike the myriad of studies on fungus–insect relationships, insect communities on ascomycete sporocarps are less explored, particularly for those in hidden habitats such as underneath bark. Here, I present my observations of insect community dynamics on Biscogniauxia spp. on oak dead wood from the early anamorphic stage to matured teleomorph stage, aided by the debarking behaviour of squirrels probably targeting on these fungi. In total, 38 insect taxa were observed on Biscogniauxia spp. from March to November. The community composition was significantly correlated with the presence/absence of Biscogniauxia spp. Additionally, Librodor (Glischrochilus) ipsoides, Laemophloeus submonilis, and Neuroctenus castaneus were frequently recorded and closely associated with Biscogniauxia spp. along its change from anamorph to teleomorph. L. submonilis was positively associated with both the anamorph and teleomorph stages. L. ipsoides and N. castaneus were positively associated with only the teleomorph but not with the anamorph stage. N. castaneus reproduced and was found on Biscogniauxia spp. from June to November. These results suggest that sporocarps of Biscogniauxia spp. are important to these insect taxa, depending on their developmental stage.
