Question

in certain situations normal species identification by rearing of larvae may not be possible. larvae may vary in size between species, but they do not have very defined species characteristics, therefore physical identification is also not possible. if an investigator only had larvae to examine, suggest a method that could identify the species that was collected from a body.

Answer 1

Molecular identification techniques like PCR-RFLP, PCR with species-specific primers, and DNA metabarcoding can be used to identify species from larvae when physical characteristics are insufficient.

Step-by-step explanation:

When traditional morphological methods fail to identify species, particularly at the larval stage, molecular identification techniques such as PCR-RFLP, PCR with species-specific primers, and DNA metabarcoding using next-generation sequencing can provide accurate species identification. These molecular tools do not require morphological expertise and allow for the identification of larvae when physical characteristics are not sufficient. DNA metabarcoding is especially promising as it utilizes environmental DNA (eDNA) to assess biodiversity from complex environmental samples, enabling the detection of even a single larva amidst a diverse community.
