Sampling Notes
areas midges ran as high as +100 in a
15 minute count to as low as 25 per sq meter
in same time interval. Some Ephydrids and
Cecids noted but in general fauna
seemed markedly depressed as contrasted
with yesterday. Marsh areas had +200 to
+500 midges per sq. meter pa 15 minutes.
Langopous were about in this situation but
in foregoing ones present and were taking a
high percentage of the midges.
Today the midge species composition became
greater with the appearance of many more
species and in more areas their presence
was noted than previously. Towards late
afternoon 3-5 they began to gather in groups
as the wind abated and perform their "Dance".
Several (7) Bombyx spp were seen
in flight over Betasites areas and
apparently were not visiting the flowers which

many more tapeworms an ant as cockleburs
and some Salsifages. Coming out of old
lemming holes are many Tepulids (small sp.)
and some of the smaller midge as well
as a few Fungivoridae and Muscividae. Many
