hi what’s that bug?
this butterfly was seen along the “stump trail” area of grant’s grove, in king’s canyon national park CA, on july 14, 2014.
is it a california sister or a lorquin’s admiral? and what is the difference?
thank you,

Lorquin's Admiral

Lorquin’s Admiral

Hi Clare,
This is a perfectly timed submission as we just posted a closed-winged view of what we believe to be a Lorquin’s Admiral, but since we could not see a dorsal view, we can’t be certain.  This is most certainly a Lorquin’s Admiral, and it is wonderful to get two views of the same individual.  According to Butterflies Through Binoculars The West, on the Lorquin’s Admiral:  “FW [forewing] apex has a linear orange patch that reaches the outer margin.”  The same source states of the California Sister:  “FW apex has a large round orange patch that doesn’t reach the outer margin.”  That said, the same source indicates the two species look very similar, but the Lorquin’s Admiral is usually associated with willows and poplars, especially near streams while the California Sister is generally associated with oak woodlands.

Was on vacation in Truckee CA and found this large beatle under a cushion for the patio chair. It was between the size of a quarter and a fifty cent piece. Slow moving and seemed to be waiting for the morning sun. A bit of a shocker!

Yellow Douglas Fir Borer

Yellow Douglas Fir Borer

Hi Warrren,
This impressive beetle is a Yellow Douglas Fir Borer,
Centrodera spurca, and we have sporadic sightings as postings on our site.  According to the Oregon State University Insect ID Clinic site:  “This is a common long horned beetle in the west that feeds under the bark of Douglas-fir as a larva. The black spots on the sides of the beetle distinguish it from some of the other species that occur in Oregon .”

Thanks for the information. So this is the Beatle that we have had trouble with killing the trees.  Right?

Hi again Warren,
You dropped an “r”.  To the best of our knowledge, the Yellow Douglas Fir Borer is not considered a significant problem regarding killing trees.

Found this in my backyard, but have never seen it before.

Lesser Peachtree Borer

Hi Chelsea,
Though it resembles a wasp, this is actually a Clearwing Moth in the family Sesiidae, and many members of the family are effective mimics of wasps, a physical attribute that acts as protective mimicry.  The defenseless Clearwing will be avoided by many predators who have previously been stung by wasps.  Many Clearwings look similar, and we will attempt to identify your species later today as we now have some house keeping to which to attend.  You can see many examples of Clearwing Moths on BugGuide.
  Though we at first claimed we would attempt a more thorough identification later, we decided to give it a quick try, and we believe this is a Lesser Peachtree Borer, Synanthedon pictipes, based on images posted to BugGuide where it states:  “Larvae tunnel under the bark and in the twigs and branches of cultivated and wild peaches, plums and cherries (Prunus), Amelanchier, apples (Malus spp.) and pears (Pyrus) (all Rosaceae).”

Subject: Morning Cloak Caterpillars?
Location: Saint John, NB Canada

I found this congregation of caterpillars on the branch of my willow tree last night. This morning they had abandoned that branch, leaving clumps of black, and had relocated to a higher branch. I am located in Saint John, NB Canada and have never encountered these before. Based on what I’ve seen on the internet, I believe they are Mourning Cloak Caterpillars but I was hoping someone could confirm that makes sense. I’m also wondering if these are dangerous and should heed any warnings. I’m not a creepy crawly fan so I haven’t gotten too close but I’ve taken a couple of photos zoomed in as much as possible.

Mourning Cloak Caterpillar Aggregation

Mourning Cloak Caterpillar Aggregation

Hi Jennifer,
Though you image lacks critical detail, there are enough similarities to presume these are Mourning Cloak Caterpillars.  Your very descriptive account of the sighting supports that supposition as willow is a common food plant.  Mourning Cloak Caterpillars frequently feed in a group, known as an aggregation, a more accepted term for a group of caterpillars than the term congregation.  Mourning Cloak Caterpillars are not considered dangerous, but the spines can cause a painful prick if they are carelessly handled.

Dear Bugman,
We found this bug while sweeping our porch today. Both the six-year-old bug expert I was babysitting and myself could not identify this insect. Your help would be greatly appreciated! Thank you very much for your time!

Dear Electronically,
Green Lacewings like the one in your image are important predators that feed upon many agricultural pests, including Aphids.  Both adults and larval Lacewings feed on Aphids.  Green Lacewings are sometimes called Goldeneyes.

Birdwing Butterfly

Golden Birdwing Butterfly

Dear Collin,
Butterfly habitats are not natural settings for butterflies, and it can be difficult to identify unknown species without knowing the country of origin, which is one method we use to search for identifications.  Additionally, the quality of your friend’s images is very poor, which is also detrimental for identification purposes.  We do know that one image is of a Birdwing Butterfly in the tribe Troidini.  It appears to be in the genus
Troides.  You can compare your image to this image of a female Troides rhadamantus from the Goliathus website.  As you can see from this FlickR image, the Golden Birdwing, which is the common name for Troides rhadamantus, is a resident in the Chicago Botanic Garden Butterfly House, which is a good indication it can be found in other butterfly habitats that often use the same breeders to obtain stock.  Let your friend know that butterfly habitats often have displays with images that assist in identifying the residents.  The Westford Butterfly Place has a website with a gallery.
