本文研究了同域分布的三种比利时萤火虫幼虫的光谱特性。进行体内光谱研究以比较生物发光光谱。实验室饲养的雌性L.而紫球藻则是用另一种更精确的方法记录下来的。的平均峰值波长（λ（最大值）= 546 nm）和形状的单峰发射光谱是视觉上相似的幼虫的所有三个物种。测定了雌成虫L.在546和551 nm之间的幼虫生物发光的峰值在同一范围内。幼虫L的半峰强度带宽略大。与半翅目原蜱（70 +/- 10 nm）相比，绿球藻（77 +/- 4 nm）。幼虫的带宽。splendidula的带宽（77 +/- 8 nm）与其他幼虫相比没有差异，而雌性的带宽稍窄（68 nm）。讨论了萤火虫幼虫和其他发光甲虫幼虫生物发光颜色和绿色发光保存的生态学意义。
We studied the spectral characteristics of the larvae of three sympatric Belgian species of fireflies, Lampyris noctiluca, Phosphaenus hemipterus and Lamprohiza splendidula. An in vivo spectral study was performed to compare bioluminescence spectra. The emission spectrum of a laboratory reared female L. noctiluca was recorded by a different, more exact method. The mean peak wavelength (lambda(max) = 546 nm) and shapes of the unimodal emission spectra are visually similar for the larvae of all three species. The emission spectrum of the adult female L. noctiluca peaked in the same range as the larval bioluminescence between 546 and 551 nm. The bandwidth at half-maximum intensity was slightly greater for larval L. noctiluca (77 +/- 4 nm) compared with P. hemipterus (70 +/- 10 nm). The bandwidth of larval L. splendidula (77 +/- 8 nm) was not different compared with the other larvae, whereas the females' bandwidth was somewhat narrower (68 nm). The ecological significance of the color of bioluminescence and conservancy of green emission in larval fireflies and other luminescent beetle larvae is discussed.
