Chironomid larvae (Diptera: Chironomidae) are ubiquitous, abundant and highly diverse (both taxonomically and in terms of function) in stream ecosystems. Does anyone have a study or diagram quantifying or illustrating energy transfer through this family of macroinvertebrates in the lotic food chain?

I hope it might help you.
Callisto have some other studies on chironomids.

Structure and Dynamics of Matter and Energy Flows
by Heterotopic Insects Imago Emergence Across the «Water – Air» Surface
of Lakes in Volga River Floodplain
I. V. Demina, М. V. Ermochin, N. V. Polukonova
Abstract
The flow of matter across the border «water – air» of Cholodnoe Lake in 2008 was 0.35 g/m2 (dry weight), the energy flow – 1.87 kkal/м2, the biogenic elements flow : carbon – 0.18 g/m2, nitrogen – 0.04, phosphorus – 0.004. The basis of this flows are large species of chironomids, mayflies, chaoborids and medium-sized chironomids, but with several generations in the year and high numbers in benthic communities. For similar in biotopic characteristics and species composition floodplain lakes is typical similar level of exchange processes, which occurs with heterotopic insects emergence.
Key words: heterotopic insects, floodplain lakes, flow of matter, flow of energy, biogenic elements, chironomids.
