   Jeremy Tatum writes:  This bug came into my Saanich apartment this morning.    Some bugs can deliver a painful bite; others can’t.  I don’t know whether this one can or cannot – I don’t care to find out by experiment.

  More miscellaneous invertebrates by Ian Cooper.

Jeremy Tatum writes:  The conspicuous dark-bordered pale dorsal stripe on the caterpillar below is more pronounced than is usual for Noctua pronuba, so it may be something else – nevertheless I am fairly certain that it is indeed N. pronuba.

Jeremy writes, of the fly below:  I don’t know what species this is.  In spite of its short antennae, I think it is of the group Nematocera (thread-horns) – a female (the males usually have longer and more ornate antennae).  If anyone knows what it is, please do let us know.
