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.

Booklice

Dear Agustin,
These are Booklice, and according to BugGuide, they are found:  “under bark, in ant nests, in homes” and “worldwide and across NA; many spp. are now nearly cosmopolitan or otherwise widely spread through agency of man, mostly with stored products.”  According to Charles Hogue in Insects of the Los Angeles Basin:  “Although it is a contributor to the allergens found in house dust and its feeding may do minor damage to book bindings and paper, the presence of the Book Louse is usually no more than an annoyance.”  According to DenGarden:  “Booklice are itsy, bitsy little bugs – about 1/16 ” long and they are not actually lice at all, so although they are harmless, they are still bugs. If you’ve got any dried out, or decaying plants, you might find these little critters enjoying a plant buffet, or they may even be lurking around your stored food. The head and abdomen appear large, and the midsection is more narrow. Huge, compound eyes protrude from the sides of the head. They also have thread-like antennae that sweep backward toward the abdomen. Not all booklice have wings, but some do (usually the booklice that stay outside), and when they do, there are four of them – two smaller front wings and two larger back wings. Most of the ones you will be hunting down should be wingless booklice.  Booklice really love paper, so you might find them on bookbindings, photographs, or even your wallpaper. You can look for them to thrive in a dark basement or storeroom, if you have one, and if you have a second home that you close up for part of the year, they have probably set up residence there as well. If you live in an older, loosely-constructed home, there are probably a lot more booklice living there than people. You may need to invest in a good magnifying glass to see them, but they are there.”

Found hundreds of small bugs on a woodworking project in the garage.  I used a air compressor to blow off as many as possible but there are still some that are on my project.  Any idea what these are and if they are destructive?  Any advise on removing them?  The best guess I have is that they are booklice.

Booklouse

Dear Chris,
This is a Booklouse and the presence of it and its hundreds of friends on your woodworking project is more an annoyance than a problem.  According to BugGuide:  “many spp. are now nearly cosmopolitan or otherwise widely spread through agency of man, mostly with stored products.”
