(victoria bc canada) this beatle was flopping around on its back on my driveway at about 1030pm
the antennea are wet in the picture but are much larger in real life and they seam to spread out like a feather with about 4 or 5 points
you cant see by the picture but it has quite large eyes
oh ya and it hisses
this is the ten-lined June beetle. Yes they do hiss especially when disturbed. They feed off the needles of coniferous trees.
Larvae hatch, burrow down in the soil and feed on roots of shrubs, trees, require 2-3 years to reach maturity. Pupation is in underground chambers. Adults do come to lights at night so perhaps you have light on the garage?
The antenna is quite large!
Thanks for the photo!
