365Caws is now in its 16th year of publication. If I am unable to post daily, I hope readers who love the natural world and fiberarts will seize those days to read the older material. Remember that this has been my journey as well, so you may find errors in my identifications of plants. I have tried to correct them as I discover them. Likewise, I have refined fiberarts techniques and have adjusted recipes, so search by tags to find the most current information. And thank you for following me!

Western Conifer Seed Bug, Leptoglossus Occidentalis
Day 363: Today's feature could be called "Everything You Wanted to Know About the Western Conifer Seed Bug But Were Afraid to Ask." This 3/4" insect was first noted in the western US where it can cause significant damage to conifer seed crops. Native to our forests, it is particularly fond of Douglas-fir seed which is consumes in large quantities by the adults prior to their retreat into overwintering sites. Nymphs feed on the softer tissues of needles and tender, developing seed during the months of spring and early summer. Adults are most frequently seen in late autumn as they search for suitable shelter which, much to the consternation of human residents, often includes the interior spaces of homes and offices, but other than being a nuisance, these insects pose no danger to people or pets. A true "leaf-footed" bug (Coreidae), the insect's hind legs exhibit a widening of both sides of the tibial area of the hind leg, visible here in the lower left. A similar species demonstrates this flare on only one side of the leg. The insects' range is now known to extend across the northern parts of the US and into Canada.

Leptoglossus Occidentalis, Western Conifer Seed Bug
Day 366: Yes, you get a bonus post! 2016 was a Leap Year, and I was fortunate that Leptoglossus didn't take that literally. As it is described in "Insects of the Pacific Northwest," it is a common species but rarely seen because it spends its life in the forest canopy. I suspect it was dislodged by yesterday's wind, although why it took refuge on the handle of my watering can is anyone's guess.
One of the distinguishing characteristics of the Coreidae (squash bugs) is the flattened segment of the hind leg, visible in this photo. It may serve as additional camouflage, breaking the linear profile of the leg into something more leaf-like and hard to see. Leptoglossus has an additional defense mechanism if its disguise fails. It carries scent glands which emit a foul odor when the insect is disturbed.
