MARCH Dominant Chironomld Larvae P â P bellus C ⢠C plumosus M- Mlcrocricotopus G â Glytotendipes. JUNE Distribution and dominance of chironomid larvae at Big Bear Lake synoptic study sites, March and June 1977. P. bellus was generally the most abundant chironomid at the main study sites but C. plumosus, being much larger, generally dominated the standing crop (Figure 5). P. bellus was generally the most abundant larvae at the midlake sites and at the lakeward bay sites during the synoptic studies (Figure 4). C. plumosus was the most abundant larvae at most other synoptic sites and dominated chironomid standing crop at almost all synoptic sites. P. bellus density ranged up to ~ 4550 larvae ⢠m"2 in the March synoptic and to ~ 1660 larvae in the June synoptic while C. plumosus density ranged up to ~ 2700 and ~ 2200 larvae ⢠m~2 in the March and June synoptic, respectively. Chironomid densities were uniformly low at all synoptic sites in September and December 1977. P. bellus density and standing crop peaked in the spring in both 1977 and 1978: 4850 ⢠rrT2 ( g AFDW . rrT2) in 1977 and ~ 1450 ⢠m~2 ( g AFDW . m-2) in 1978 (Figure 5). The pattern of P. bellus seasonal abundance (Figure 5) reflects inefficient sampling of early instars. The mesh size used did not effectively retain early instars. Abundance would be expected to peak somewhat.
