Abstract We provide a record of spongillaflies (Sisyridae) with an associated host sponge from a population found in Spring Creek, Utah. We monitored the population for the 2016 field season to identify the insect and its associated host sponge and to establish the seasonal period of the insect’s presence in the adult stage. We also evaluated the commonly used sampling techniques of sweeping and light trapping and made natural history observations. We identified the spongillaflies as Climacia californica Chandler, 1953 and the sponge to be Ephydatia fluviatilis (Linnaeus, 1758). We collected 1726 adults, and light trapping proved to be the superior collecting method. The population was characterised by a two-week emergence peak occurring at the end of July to beginning of August followed by a steep decline. Other habitats within the state contained E. fluviatilis and should be sampled using light traps at times when peak abundances are predicted to further understand the distribution of C. californica across the state and the Intermountain West. urn:lsid:zoobank.org:pub:F795281F-0042-4F5F-B15B-F6C584FACF2B

Climacia californica Chandler, 1953 (Neuroptera: Sisyridae) 在犹他州：分类特征、宿主关联和季节性发生

摘要我们提供了海绵蝇（Sisyridae）和相关宿主海绵的记录，这些海绵来自在犹他州 Spring Creek 发现的种群。我们监测了 2016 年野外季节的种群，以确定昆虫及其相关宿主海绵，并确定昆虫在成虫阶段出现的季节性时期。我们还评估了常用的扫描和光捕获采样技术，并进行了自然历史观察。我们将海绵蝇确定为 Climacia californica Chandler，1953 年，海绵确定为 Ephydatia fluviatilis（Linnaeus，1758 年）。我们收集了 1726 名成年人，事实证明光诱捕是最好的收集方法。种群的特点是在 7 月底至 8 月初出现两周的出现高峰，然后急剧下降。该州内的其他栖息地包含 E.fluviatilis，应在预测峰值丰度时使用光阱进行采样，以进一步了解 C. californica 在该州和 Intermountain West 的分布。urn:lsid:zoobank.org:pub:F795281F-0042-4F5F-B15B-F6C584FACF2B
