North American forest systems are significantly impacted by spongy moths (Lymantria dispar Linnaeus). It is unclear, nevertheless, how are the invasion risks of spongy moths from Asia and Europe in North American relative to each other. In this study, we compared the potential ranges of spongy moths from Asia (ASM) and those from Europe (ESM) in North America, and investigated the range shifts between spongy moths in North America (NASM) and ASM and ESM. ASM and ESM would occupy larger potential ranges in North America than NASM, i.e., 7.16 and 6.98 times, respectively. Thus, one should not undervalue the invasive potential posed by spongy moths from Asia and Europe. Compared to ESM, ASM displayed larger ranges in North America. It is likely due to ASM's tolerance of more variable climates. Consequently, even though ASM was more recently introduced to North America than ESM, it's possible that the former has higher invasion risk in North American.
北美森林系统受到舞毒蛾（Lymantria dispar Linnaeus）的显著影响。然而，来自亚洲和欧洲的舞毒蛾在北美的入侵风险相对彼此如何并不清楚。在本研究中，我们比较了亚洲舞毒蛾（ASM）和欧洲舞毒蛾（ESM）在北美的潜在分布范围，并调查了北美舞毒蛾（NASM）与ASM和ESM之间的分布范围变化。ASM和ESM在北美将占据比NASM更大的潜在分布范围，分别为7.16倍和6.98倍。因此，不应低估来自亚洲和欧洲的舞毒蛾所带来的入侵潜力。与ESM相比，ASM在北美显示出更大的分布范围。这可能是由于ASM对更多变气候的耐受性。因此，尽管ASM比ESM更晚被引入北美，但前者在北美可能具有更高的入侵风险。
