Western Conifer Seed Bug (Leptoglossus occidentalis)

I’ve been stuck in the house all week with the flu…a BAD case of the flu. You don’t want it! Trust me. So, what does the very bored, sniffling, coughing entomologist do to pass the time when she’s sick? Why play with bugs of course!

My honey brought me this from the back deck…(such a thoughtful man!). fullsizeoutput_184b.jpeg

I wonder if he knew that had he not been more careful, our house could have been filled with “le pew de le bug,” a very unpleasant odor! While I probably wouldn’t have suffered (since I’m all stopped up), he certainly would have noticed.

So, what is this bug? Well, it’s not a “bug,” it’s an INSECT. You know….6 legs, chitinous exoskeleton, antennae, three main body parts (head, thorax, and abdomen).  More specifically, THIS INSECT is a Western Conifer Seed Bug (Leptoglossus occidentalis).  It is classified in the order Hemiptera, family Coreidae (Leaf-footed Bugs and Squash Bugs).

No….please don’t take that literally.  I’m certain this fella (or femme) would not like to be “squashed!”  I don’t advocate squashing any insect.  They’re ALL interesting…in one way or another.

The Coreidae or Squash Bugs are medium to large in size.  They are usually brownish colored.  This one has what I would describe as the beautiful color, Bronze! Please also note the leaf-like hind tibia, a feature characteristic of some species in this particular family. img_1869-2

What does it eat? It feeds on vegetation.  Check out the very long, piercing Rostrum or Proboscis tucked carefully along the underside of this one’s body.  western-conifer-seed-bug-leptoglossus-occidentalis

The Rostrum is used like a straw to suck the juices from conifers including Douglas Fir (Pseudotsuga menziesii) and Lodgepole Pine (Pinus contorta).  Other species are vegetable pests.  Hence the “Squash Bug” moniker.  It also has the characteristic SCENT GLANDS that will secrete the particularly stinky odor if you poke it too much when you are trying to get it to pose for a picture!  “Le pew de le bug!”
