Stinging Slug Caterpillar from Singapore

Neon Green Caterpillar Fri, May 8, 2009 at 5:35 PM
Hi
I found this caterpillar under a leaf in a forested area near my home. I’ve never seen a neon coloured caterpillar like this before. Could this be a stinging slug caterpillar? I’m pondering as I live in Singapore, and so far all the documentation I’ve read about stinging slugs don’t come from this area of the world. Thanks!

Stinging Slug Caterpillar

Hi Jeremiah,
This is certainly a Stinging Slug Caterpillar in the family Limacodidae .  While we are not certain of the species identification, perhaps one of our readers will write in with an answer.

This bug was found outside, in the twin cities metro are of Minnesota. The size of the bug was rather small, a few centimeters. I hope the image is good enough for you to see and hopefully figure out what it is.

American Pelecinid

Dear TK,
The very unique American Pelecinid, Pelecinus polyturator, is not likely to be confused with any other North American insect. Your specimen is a female, and she uses her unusual abdomen to parasitize the grubs of scarab beetles. According to BugGuide: “Parasitoids of insect larvae that feed on decomposing wood, etc. These include larvae of scarab beetles, esp. May Beetles ( Phyllophaga ). Also reported to parasitize wood-boring insects. Female thrusts ovipositor into soil to detect host, lays one egg on each. Pelecinid larva burrows into the beetle larva, killing it. Wasp larva scavenges remains and pupates there in soil. ” BugGuide also indicates this surprising information: “In North American populations, males are rare, and reproduction is apparently largely by parthenogenesis (Brues, 1928). In tropical populations (or species), males are more abundant.” Lastly, BugGuide also states: “Typically August-September. Reported July-August (Minnesota), June-September (North Carolina)” which could make this early sighting another indication of global warming. Insects are often quite adaptable, and changes in their habit force them to adjust quickly as their life cycles are generally less than a year.

Sheridan’s Green Hairstreak: State Butterfly of Wyoming

Wyoming’s state butterfly
Sun, May 10, 2009 at 5:39 AM
Hi Lisa Anne and Daniel, this past winter Wyoming was first designated a state butterfly, the Sheridan’s Green Hairstreak. The process was begun by some Sheridan County third grade students as a civics project. They wanted it to be the state insect but a sponsoring Sheridan legistator suggested naming it the state butterfly instead, “to leave the insect open for other students who may want to designate the state spider, for example”…insert your own joke here.
Anyway, it is a beautiful creature.
Peace,

Immature Greater Angle-Wing Katydid

Mystery Bug with Tiny Wings!
Tue, May 5, 2009 at 1:27 PM
I’ve been meaning to write this letter for a long time! I have to apologize, because I’m sure this bug is “out of season” (?) right now. We found this little guy climbing on one of our baby willow trees on August 19, 2008. He looks to me like a kind of grasshopper, but I bet you’ll tell me I’m wrong! I was slightly perplexed by his tiny wings in proportion to his large body, which was a little smaller than my thumb (around 1.5-2 inches maybe?). I apologize for not grabbing a ruler or something… I’m kind of embarassed to say I was concentrating on being artistic, haha. If you could give me any insight into who this little guy is, I’d greatly appreciate it. Thank you so much!
Sincerely, Jess K.

Dear Jess,
This is a Katydid and it is immature as indicated by its still developing wings. We are relatively certain it is a Greater Angle-Wing Katydid, Microcentrum rhombifolium , as evidenced by an image posted to BugGuide. We will be traveling to Youngstown in about a month to visit family.

Wow, I never would have guessed a katydid… but I guess I’ve never really seen one until then, either, haha. Thanks for your help, and best wishes for your safe travels to Ohio!

Lime Hawkmoth

Lime Hawkmoth

Hi Tom,
We believe this is the second time we have received a photo of the Lime Hawkmoth, Mimas tiliae.  The common name is derived from the food tree, the Linden, which is called the Lime Tree in England.  According to UK Moths, According to that website it is:  “A reasonably common species in the southern half of Britain, it was most frequent in the London area, where there are still extensive tree-lined avenues. In recent years its distribution has spread northwards and is now regularly found well into North Yorkshire and beyond. “  We believe the range expansion is due to global warming.

Another BUG OF THE MONTH MAY 2009: 17 Year Locusts, Scientists surprised By Unexpected Emergence Of Periodical Cicadas — Four Years Early

Hello. This morning while putting on my shorts, which contained this lovely thing, it stung me. I’m still not feeling well and have been unable to find out what it is.
We’ve live in this area for 4 years now, Central Virginia, and have never seen this before. Although now we are seeing them everywhere.

periodical cicadas early 2009 300x251 Another BUG OF THE MONTH MAY 2009:  17 Year Locusts,  Scientists surprised By Unexpected Emergence Of Periodical Cicadas    Four Years Early

Periodical Cicadas emerge early

Hi Kimberly,
We were so shocked by your report and photo of Periodical Cicadas or 17 Year Locusts, that we immediately did some research to find out what brood this was. We located a very interesting piece online on Science Daily that states: “The cause of these early emergences is unknown, but [Gene] Kritsky, in a paper to be published in the Proceedings of the Indiana Academy of Science, has found evidence suggesting that mild winters can affect the trees that young cicadas feed upon which in turn interferes with the cicadas’ timekeeping resulting in their emerging early. ‘This phenomenon might be another biological response to increasing temperatures,’ Kritsky said. ” Can this be yet another piece of evidence that global warming is affecting the environment in very telling ways? Even more puzzling is that you were bitten. Cicadas do have sucking mouthparts and perhaps you were mistaken for a succulent sapling. Cicadamania indicates this is Brood II on an accelerated emergence. Generally, every 14 or 17 years, there is a mass emergence of millions of Magicicada individuals. They breed, provide food for birds and other wildlife, lay eggs and die. The young hatch, bury themselves underground, live there for 13 or 17 years, and then emerge as a new swarm. The 17 Year Locust, Magicicada septendecim, is one of the oldest living insects.

We had one in the house last week and killed it not knowing what it was. They are huge!!!
I’m guessing the fact that I put my shorts on with him in them probably scared the bejesus out of him and that’s why he bit me? I know it freaked me out. I don’t think I’ve ever gotten out of my shorts so fast.
Right now, it just mostly itches like a dickens.
We live in Chase City, Virginia. (acutally a little outside of it) These past couple of months we have done tons of excavating. First for a riding ring, then we had to lay a new septic drain field and last we had to lay a new well line. (sucky year for our yard).
Could all of that digging brought them out? We’ve also had a very large amount of rain. To the point of it being ridiculous.
I don’t know what type of trees they typically live on. We have lots of Oaks. A few momosas, pines, magnolia’s, a black walnut and a peach tree. There’s also a willow and a persimmon. (the spelling may be off on that one) We also had tons of holly tree’s but we’ve cut most of them down over the past year due to overgrowth before we bought the house.
So far, our’s in the only house around that has them. And, now that we know what they are, we won’t be so afraid of them..as long as they stay out of my clothes.
Thanks for your help.
Kim

Hi Kim,
Thanks for the follow-up information, especially since we have made this unusual occurrence a secondary Bug of the Month for May. We doubt that your excavation had anything to do with this unseasonal appearance. With the Magicicada species, there are various numbered broods that have differing and overlapping ranges. Some like Brood X, the largest of the broods which emerged in 2004, are very wide ranging. According to BugGuide: “There are four species with 13-year and three species with 17-year life cycles. The 13-year species are more southern, the 17-year species more northern.” National Geographic News indicates: “There are at least 12 broods of 17-year cicadas plus another three broods that emerge every 13 years. ‘A brood is a class year, like the graduates of 2004 who will be graduating this May,’ said Gene Kritsky, a biologist and cicada expert at the College of Mount St. Joseph in Cincinnati, Ohio. A brood emerges almost every year somewhere, sometimes overlapping with others. But none of the emergences matches the pure size of Brood X, which includes three cicada species: Magicicada septendecim ,Magicicada cassini , and Magicicada septendecula .” You may have an isolated pocket of Brood II since none of your neighbors have seen any. It might be that this atypical emergence is just beginning, and your neighbors homes will soon also be graced with Cicadas. Though there is a mass emergence, all individuals do not burrow to the surface on the same day. We expect that this atypical emergence is just beginning, and we will be getting additional reports from other areas in the coming days. Once again, thanks so much for allowing What’sThat Bug? to be among the first websites to report this occurrence this year. National Geographic News also has this to say about the life cycle of the Periodical Cicada: “After the cicadas have counted 17 years—’we really don’t know how they count the years,’ Kritsky said—they are ready to emerge, which usually happens in late spring when the soil reaches a temperature of about 64 Fahrenheit (18 Celsius)” and “Some scientists believe the mass emergence of the cicadas is part of a survival strategy. With so many of them, they collectively satiate their predators within a few days. Then the billions left uneaten are free to mate.” In 2000, several hundred thousand members of Brood X emerged in Cincinnati. According to National Geographic News’ 2004 coverage: “The outbreak was big enough for the cicadas to satiate their predators, sing, mate, and lay eggs. ‘If [the year 2000 Cincinnati nymphs] come out in 2017, we will have seen the evolution of a whole new brood,’ Kritsky said. ‘That’s cool.’” So Kim, your yard may be ground zero for the appearance of a new brood.

Update: Can Cicadas Bite?
10 May 2009
We have been trying to find out this information, and there is a very amusing posting on Cicada Mania that indicates they may bite. It states: “Technically cicadas don’t bite or sting; they do however pierce and suck. They might try to pierce and suck you, but don’t worry, they aren’t Vampires nor are they malicious or angry — they’re just ignorant and think you’re a tree. ” We would be more inclined to believe that Kim was scratched by the clawlike front legs.

Aloha Daniel -
About the cicada bite – to help with itching.
This is usually a great toxin extractor – a poultice of water and baking soda.
Used it as a child on bee/wasp stings. Use it over here in HI for centipede bites.
Non toxic, everyone has it around their kitchen. Cool water temp soothes the bite zone.

Bite Update: cicada bite
Sun, May 10, 2009 at 9:49 AM
A few years ago, while working in a state park nature center in Indiana, a young (6 years old) entomologist brought his latest aquisition, a cicada, to show me. I picked it up and let it crawl on my thumb. When I was ready to give it back, the thing wouldn’t let go, and decided to press that sucking mouth part into my thumb. It was pretty painful. They can DEFINATELY bite (or perhaps STAB is a more appropriate term).
When talking to the public about insects, which I do often, I try to point out the difference between “does it bite?” and “can it bite?” Many insects can bite, but are very unlikely to do so. I suspect that a person could pick up 100 cicadas before they got bit by one.
I was once bitten by a praying mantis while feeding it a cricket. Part of the cricket dropped on the back of my hand and the praying mantis went down to eat it and chewed on my hand instead… and continued to chew while I yelped in a surprising amount of pain. I had to pry it off my hand with a piece of cardboard. It itched like crazy for days. I still have a tiny scar. This is an exceptional case, but makes me think twice about what we tell people, especially bug lovers, about what can and cannot bite.

Thanks Vince, for your first hand account. We are just guessing, but we suppose your thumb is considerably tougher than Kim’s thigh, and if the thumb skin could be penetrated, the thigh might be like butter.

Eyed Elater

Hi April,
Your letter is so amusing.  This Eyed Elater was not really looking back at you.  It just appears to be looking back at you.  What you think are eyes are just eyespots.  These eyespots help to discourage predators, especially birds.  The birds see the large “eyes” and think a far larger creature is at hand, possibly a snake.  Eyed Elaters are Click Beetles that can right themselves if they are on their back by snapping their bodies, propelling themselves into the air, and flipping to land right side up.

Freshwater Shrimp???

an aquatic lawn shrimp?
Wed, May 6, 2009 at 3:11 PM
hi, i have found these swimmers in a stray cat’s drinking bowl that someone has set up in the woods, not far from a busy road. ill take it as the bowl is never dumped out if these lived in them. fortunately i had a big ziploc bag and collected the specimen, and was kind enough to wash their bowl and poured bottled water in it, and was greeted by two grateful beautiful longhaired cats. i was able to collect 11 of them but some died in transit, i placed the little guys in my fishtank and its been a few hours and theyre still okay. i took pictures and a couple videos with my fujifilm camera aided with a 10x triplet magnifier with the intent to send in the photos here, i am actually surprised that on the frontpage was a photo of dead lawn shrimps and they looked very similar to what i have found, except i found my little guys a live and swimming in a kitty bowl.

gammarus 2 299x283 Freshwater Shrimp???

Freshwater Shrimp

Dear dogafin,
Your observation that your specimens resembled the Lawn Shrimp was quite astute. We are certain that your specimens are also Crustaceans, quite possibly Freshwater Shrimp in the genus Gammarus. Gammarus and Lawn Shrimp are both in the order Amphipoda. We located a fishing website that has information on Gammarus which are also known as Scuds. The The Backyard Arthropod Project A Field Guide to the North Side of Old Mill Hill, Atlantic Mine, MI also has some good information. We might be way off base here with the genus ID because the location was so odd. We can only guess that at one point the cat bowl was filled with water from a pond inhabited by the Crustaceans. We gladly welcome a professional identification on this somewhat odd sighting.

Dear WTB,
I’ve worked on benthos of the Great Lakes and inland lakes in Michigan for close to ten years now and have seen a few amphipods in that time. From these pictures its difficult to say much more than an amphipod. If there’s a pond or lake near by its possible that these could, at the very least, be in the family gammaridae but the could also be Hyallela. The way to determine this is to see if there are accessory flagella (small segmented appendage) on the 4th segment of the first (top pair) of antennae. If there’s no flagellum its Hyallela; if there is a flagellum its more likely to be Gammarus or at least in the family gammaridae.
