A description of the third instar larva of Hydaticus bimarginatus (Say) (Coleoptera: Dytiscidae).(Report)
|
ABSTRACT
Larvae collected from a Georgia temporary habitat were identified as Hydaticus bimarginatus based on the presence of trilobed pre-mentum and distribution records. These larvae have well-developed series of natatory sensilla characteristic of nektonic dytiscids with the distribution of the spiniform sensilla corresponding to patterns of previously described larvae of Dytiscinae. Modifications of the protibia and protarsus are described and interpreted as a complex cleaning apparatus.
Key Words: Dytiscidae; Hydaticus bimarginatus; larva; life cycle; morphology; ...
