The effect of larval competition on adult size and egg to adult development time has been investigated in laboratory populations of the seaweed fly, Coelopa frigida. Increased larval density results in longer development times and smaller adults, suggesting a strong interference element to the competition. This may be due to a limiting rate of food supply rather than interactions between larvae. The relationship between development time and size suggests that both these characters are involved in control of the onset of pupation. C. frigida is polymorphic for an inversion on chromosome I. Differences in relative viability between the karyotypes are not related to the development time or size differences.
在海草蝇（Coelopa frigida）的实验室种群中，研究了幼虫竞争对成虫大小以及卵到成虫发育时间的影响。幼虫密度增加会导致发育时间延长且成虫体型变小，这表明竞争中存在强烈的干扰因素。这可能是由于食物供应速率受限，而非幼虫之间的相互作用。发育时间和体型之间的关系表明，这两个特征都参与了化蛹起始的调控。海草蝇在染色体I上的倒位具有多态性。不同核型之间相对活力的差异与发育时间或体型差异无关。
