Kowalyk (1985). Cephalic setation. Generic identification of subfossil Tanypodinae. material is most readily accomplished
slides should be stored horizontally immediately after they are prepared. Chironomid identification. A biological microscope is used for identification (x40 magnification). Chironomid head capsules (see Figure 2) are identified by using a range of keys and identification guides (e.g., Cranston, 1982; Oliver and. Roussel, 1983
(2007) guide would present a visual guide of the chironomids found as presented here and in Larocque and Rolland (2006). This exercise is time-consuming, it is difficult to find head capsules which are well preserved and positioned appropriately on the slide to make pictures, and taxonomic aspects used for many years
everyone identifying chironomid larvae should have is “Chironomidae of the Holarctic Region. Keys and Diagnoses. The keys in this Ohio EPA guide should always take precedence when identifying Antennae retractile into head capsule; head capsule with ligula bearing 4-8 teeth; the mentum usually poorly developed,

Chironomid larval head capsules are also well preserved in lake sediments and can be used to make quantitative reconstructions of palaeoenvironmental change. The larval stage, however, has an unjustified reputation of being difficult to identify. For this reason, in routine biodiversity assessments and environmental
head capsule morphology has been used to identify wild larvae of Chironomidae. head capsule morphology for taxonomic identification is head capsule deformity. Head capsule deformities of chironomid larvae can be a common biomarker for Cranston, P.S. (2000) Electronic identification guide to the Australian.
