Thinking about the scene a little more and talking to a mate
about it last night ... it turns out they well may be moving water
species. The hatches occurred in one bay ... with an inflowing
brook. Guess where the prevailing breeze was from! I'm almost
convinced that stream hatching pupa and adults were being washed
and blown into the bay - was definatley localised. Add to that the
rise and fall of the lake over a hydro season eggs could be layed
in flowing water and pupate in near still!

Judging by what you describe, you're benefiting from some biological
drift into the lake. You would think fish should stack up there.


The lake dwelling stick pupa here apparently crawl out to
complete their cycle so it is unlikely that pupa of those were
being taken near the top in open still(ish) water.

Leptoceridae? They'll swim in their cases so they can be imitated
with a moving case pattern. According to that site, there are some 14
genera and 80 species in Oz
