Figure 3. a in EVIDENCE OF PARTHENOGENETIC POPULATIONS FROM THE PARATANYTARSUS LACCOPHILUS SPECIES GROUP (DIPTERA: CHIRONOMIDAE) IN THE ALASKAN ARCTIC Abstract Introduction

Figure 3. a) A freshly emerged, virgin individual of the Paratanytarsus laccophilus species group (arrow) clinging to the mesh lid of the new rearing cup to which it was transferred. The isolated female was then monitored daily for signs of oviposition. b) The pupal exuviae (PE) collected from the larval rearing cup, used to confirm species-group identification. Note the diagnostic patterning on abdominal tergites III and IV (Wiederholm 1986). Scale bar in (b) = 0.5 mm.
