Moss Mimic Katydid from Costa Rica

Katydid Costa Rica

Hi, again! I love this site! Here are two pictures of what looks to me like a katydid. It resembles the Panama Sylvan katydid – Acanthodis curvidens that is shown on this site, but the coloration is quite different. I assume mine is a female. It was sitting on the side of a concrete block used to surround some gardening stuff. It sat very still for the photos and is about 3-4 inches long. Perhaps the genius at Harvard who identified the other katydids can have a go at this one?

Hi Mary,
We have contacted Piotr Naskrecki and we hope he will be able to provide you with a species identification of this awesome looking Katydid from Costa Rica.

Hi Daniel,
This is Haemodiasma tessellata, a gorgeous moss mimic, often found in mid-
to high elevation forests. They sometimes fly to light at night, which may
explain finding it around the house. I would be curious to know where and
when the pictures were taken.

Hi, Daniel!
Please tell Piotr that a found the moss mimic katydid two weeks ago.  I live in a rural/wooded area of Costa Rica at about 1200 meters.  It is on the Pacific slopes of the Talamanca Mountain range in southern Costa Rica.  I have two hectares of secondary highland forest (with a corridor of primary forest near a stream on the property).  I also raise organic fruits, vegetables, and medicinal plants.  I found the katydid just sitting on a concrete block near my house one morning as I was putting bananas and other fruits on a bamboo feeding platform near my bedroom window.
What does tesselata mean?  I also raise a type of live bearing cockroach called Archimandrita tesselata.  Wish I’d known bugs were so fascinating when I was young enough to study entomology more thoroughly than I did for basic biology classes.  I wound up becoming a professional field gerontologist instead.  But I was an insect collector for the Smithsonian when I lived in Florida where I also raised various insects just to watch them, do some non traumatic experiments, and learn about them.  I even wrote some tongue-in-cheek articles about the joys of raising various insects for several newspapers.
Now that I’m retired I enjoy combining my interest in living things with my hobby of photography.  There is always something new.
If you know of anyone who would like a place to stay near the Wilson Botanical Gardens and Organization for Tropical Studies research center near me while they do field studies, please tell them I have a very nice guest room available.  It would be fun to have a guest who is interested in biology.
