We encountered this lichen mimic hemipteran in Costa Rica 10 days ago. Can you help in identifying it please.
I tried previously to submit, but have now reduced the size of a single file.

Lichen Mimic Hemipteran

Lichen Mimic Fulgorid Planthopper

Hi Hugh,
How large was this Hemipteran?  It resembles a Lace Bug in the family Tingidae, but we could not locate any images of similar looking Lichen Mimic Lacebugs from Costa Rica on the internet.  Lace Bugs are quite small.  We would not rule out that it is some species of Planthopper from the superfamily Fulgoroidea.  Perhaps one of our readers will have better luck with an identity than we have had.

Hi Daniel,
It was 1.5, maybe 2 cm long. I couldn’t find anything on the net either!

That is too big to be a Lace Bug.

Comment from Hugh:  August 11, 1016
With the help of Dr Jim Lewis of the Museo Nacional of Costa Rica and Dr Jan Janzen this has been identified as Sinuala tuberculata in the Fulgoridae.

Aloha folks, You guys were so helpful the last time that I thought I’d give it another go.
I found this guy on the underside of a Cannabis sativa fan leaf (legally grown). I’m not sure if the black spots surround it are fecal matter, but some of the black spots on the bug almost looked like babies. Any help is much appreciated.

Possibly Lace Bug Nymph

Possibly Lace Bug Nymph

Dear Greg,
This is an immature True Bug, and nymphs can be very difficult to correctly identify.  Our initial guess is that this appears to be an immature Lace Bug in the family Tingidae.  According to BugGuide, they:  “Feed mainly on leaves of trees and shrubs, causing yellow spotting and sometimes browning and death of the leaves.”  Beetles in the Bush has some nice images of immature Lace Bugs.  Aloha Arborist Association has a similar looking image of the Cotton Lace Bug, with a list of plant family hosts, but Cannabaceae is not listed.  Perhaps your Lace Bug is a different species, or perhaps the information on plant host families is incomplete.

Thank you so much Daniel!  You are a saint!  I really appreciate your help and expertise.

Leaf Mimic Katydid

Dear Kimberly,
We believe this is a Leaf Mimic Katydid,
Pycnopalpa bicordata, a species we located on PBase.  There are many nice images on FlickRiver, and according to Insects and Spiders of Trinidad, it is found in your area.

I found this insect on the side of my house and I have no idea where to start for an identification. Thoughts?
Thanks in advanced

Dear Ed,
Based on this and other images posted to BugGuide, we believe your moth is a Pug, a Geometrid Moth in the genus Eupithecia.  According to BugGuide, they are   “Commonly referred to as pugs because of the short underwings.”

I found this on my fence outside, there was a spider web around it, but I’m not sure if it came from the insect or anything spider. I tried to search this insect but couldn’t find anything in relation to it, the insect has 6 legs and I’m really curious to know if it is poisonous or not. Thank you hope you can get back to me 🙂

Netcasting Spider

Netcasting Spider

Dear Christelle,
Though it does not appear to have a net, we believe this is a Netcasting Spider in the family Deinopidae, which is pictured on Brisbane Insects where it states:  ” The species in this family are large and slow moving spiders. They have long body and stick like legs. Their bodies are light brown or grey in colour. They do not build permanent web, instead, they hold the net and throw it towards their prey.”  The Spiders of Australia site has a Deinopidae page where it states:  “The net-casting spider is a common spider and is also often seen in documentaries because of its unique way of catching prey. The spider positions itself, head down, and grasps the rectangular capture net with its four front legs. If a walking insect is detected, the net is pushed over the victim that gets ensnared. Flying insects, like moths, are caught by flicking the web backwards.   The web is made of non-sticky cribellate (woolly) silk. Insects gets entangled in the wooly structure.  The spider relies heavily on its eye-sight. The eyes are arranged in three rows. Two of her eight eyes are extremely large.   The spider is active during the night and during the day she remains camouflaged on a tree bark. Her body length varies between 1.5 and 2.5 cm and they are light rusty brown coloured.” Your individual appears to be missing a leg.

We received notice from Peculiarist that the same caterpillar was submitted for twice for identification.  The correct identification is most likely a White Rayed Patch caterpillar.

I took this photo on October 2014 in Cuernavaca, Mexico. I think it may have been on milkweed, but I’m not a hundred percent sure about that. I’d appreciate any insights.

Possibly Buck Moth Caterpillar

White Rayed Patch Caterpillar

Dear Peculiarist,
We believe this is a Buck Moth Caterpillar in the genus
Hemileuca, but we have not had any luck locating any matching images of Mexican species with such dark coloration with yellow speckles.  We will contact Bill Oehlke to get his opinion.

Bill Oehlke Responds
I am pretty sure it is one of the Coloradia species, and the only Coloradia I have for Morelos is Coloradia euphrosyne. Unfortunately I d o not have an image for comparison, but I will tentatively post this image to that page. As always I request name of photographer and permission to post.

Bill Oehlke amends his original response
Elevation and date might also be helpful if you can obtain that info. Euphrosyne are known from elevations around 2000m and are thought to be pine feeders although the larval stage has not been documented to my knowledge.

Peculiarist writes back.
Thanks for the identification! I gladly give you permission to use the image for the site.
And thanks for the site, it’s very helpful to me, as I try to figure out what’s in my garden.

Update from Peculiarist:  February 27, 2016
Hi Daniel,
As I was updating my page I noticed that this is the same caterpillar I sent before (my photo folders are a bit of a mess, and I had this duplicated in another folder), that was tentatively identified as a Pine Moth caterpillar. They do look alike, but I think with the extra information you have in these three photos White-rayed Patch is a more likely match. The food tree matches.
Thanks for your help, and I’ll be more careful in sending the most complete information I can in the future.
