Twelve small groups were observed southeast of the eastern channel of the Sagavanirktok River. On 3 July, insect activity was classified as low to moderate and 370 individuals were observed within 16-18 km of the coast. Small groups were found across the study area, including areas along the Sagavanirktok and Kuparuk rivers and in the PBOF (Figure 3a)..
