Tree Cattle

Dear Jack,
We hope our response was not too late to save these benign Barklice or Tree Cattle.  Generally when insects congregate like this, they are plant pests, but Tree Cattle will not harm your tree.  They feed on lichens.

Barklice

Dear Curious,
These are benign Barklice, commonly called Tree Cattle.  They will not harm your tree. 

Thank you so. I hope for the quick reply.  I had previously sent the same photos to our pest control company and they told me the bugs treehopping nymphs that should be eradicated (for a price of course). It would appear that they were wrong.  I did look up about barklice and I know now that I should check the tree to see if it is healthy or not
Thanks again and what a great service this site does

Your letter to the bugman:  This group of insects were high up in a Cecropia tree. Some appear to be winged and others have what looks like long rear legs.

Barklice

Dear Linda,
These are Barklice or Tree Cattle in the insect order Psocoptera, and though we were not able to locate any similar looking species from Panama or surrounding countries, we did locate this somewhat similar looking individual from Bolivia on FlickR.

Daniel,
Thank you for your help. The photo was poor quality due to the bugs being so high in the tree so I am amazed that you could id it so quickly. I will study what you sent. I am curious about the winged bugs that were with the ones with large hind legs, the winged ones seemed to be herding or at least following the others.
Thank you for your website.
Linda Scott

Hi again Linda,
The winged individuals are adults, and the immature individuals have not yet developed wings.

Your letter to the bugman:  Hello,
I develop natural filled bed pillows and we recently came across a bugs in our pillows that are filled with buckwheat hulls. We are trying to get them identified to better know how to treat our problem. We normally order the buckwheat from a local supplier that imports it from Europe.  Any insight would help.

Booklouse

Dear Beatrice,
You have Booklice.  The good news is that according to Bugwood Wiki:  “Within a home booklice are almost always found in damp areas that support the molds on which they feed. Bathrooms are common areas where they are encountered. Occasionally they may build in large numbers on grain products that have been stored poorly. The common name relates to their occasional association with books, papers and fabrics where they feed on the starchy materials (e.g., glues, fillers). Booklice are considered to be very minor household pests and the arid climate of Colorado suppresses the occurrence of many species. Booklice cannot bite humans.”  The bad news is that despite being somewhat benign, the presence of large numbers of Booklice in your pillows will probably be off-putting to some customers.  Furthermore, your damp Seattle climate is probably contributing to the Booklice reproducing and increasing their numbers.

Barklice

Dear Miranda,
These benign insects are in the family Psocidae, and they are commonly called Barklice.  Based on this BugGuide image, we are relatively certain your species is
Cerastipsocus venosus.  Barklice frequently form large aggregations of both winged adults, and brightly patterned wingless nymphs as they feed upon, according to BugGuide, “accumulations of fungi, algae, lichen, dead bark and other materials that occur on tree trunks and large limbs,” leading to the common name Tree Cattle.

Barklouse

Dear VP,
This looks to us like a benign Barklouse in the order Psocodea.  In our opinion, treatment is not necessary, though when plentiful, Barklouse might be a nuisance.
