Beetle found on Potato plant-life cycle
May 30, 2010
We found this bug on a potato plant in south western Bulgaria. We have the entire life cycle from beginning to adult. Thought these would be interesting photos for you. Our Bulgarian friends said these insects come from Colorado but we don’t know what they are, maybe you can help. Feel free to post these pictures.

Colorado Potato Beetle

Dear Josh and Chantelle,
How wonderful it is that you have provided documentation of nearly the entire life cycle of the Colorado Potato Beetle, Leptinotarsa decemlineata, a species native to the mountains of Colorado.  With the cultivation of potatoes, the Colorado Potato Beetle range has spread nearly everywhere potatoes are cultivated.

According to BugGuide:  “Before the introduction of the potato in the US this beetle was confined to Colorado and neighboring states feeding on some native species of Solanum (night shade), now it has spread to most potato growing areas.  It has been transported to Europe where it has become a serious pest.

Dont know much about this bug, but a friend took a pic of it in southern CT

Dragonhunter Larva

Dear Curious,
In a general sense, this is the aquatic larva of a Dragonfly, known as a naiad.  In an attempt to be more specific, we are nearly certain it is the larva of a Dragonhunter, Hagenius brevistylus.  You can compare your image to photos posted to BugGuide.

Really, what IS this bug?

I live in central Oklahoma. Lately I have taken to wandering around my yard and taking photos of flowers or bugs or whatever catches my eye. I came back from the store and found this little guy crawling on my fence. The striking black and red caught my eye, as well as the bugs’ posture. It has long legs that are out of proportion to the length of it’s body, and it’s abdomen is not straight but stuck up. I did search your site as well as and couldn’t find anything that resembled this. Can you tell me, what is this little critter? Thanks in advance!

Immature Wheel Bug

Hi Amy,
This is an immature Wheel Bug.

Strange looking beetles
May 29, 2010
These bugs were on the playset in my backyard. I live in Minnesota, have all my life, and have never seen anything like these before! I’m wondering what they are, and if they’re harmful in any way? The definitely look exotic! The first one is a little bigger than a ladybug, and the second is about the size of 3 ladybugs.

15 Spotted Lady Beetle Larva

Spiky, Spotted Snail thing??
May 30, 2010
My friend found this bug/snail/worm thing on her playset in her backyard. It looked so unique we asked many many people if they knew what it was. No one has been able to give an answer. What is this and is it harmful, useful, or just a bug?

15 Spotted Lady Beetle Pupa

Dear Mandy and Appledoorn,
Since you both wrote to us with the same image, we are combining your letters into one posting.  The photos represent the larva and pupa of a Lady Beetle, but we need to do some research to try to identify the exact species.  We quickly matched the pupa to that of the 15 Spotted Lady Beetle based on a photo posted to BugGuide.

What To Do With Rosy Maple Eggs?
May 30, 2010
My 4 1/2 year old daughter and I visit your website regulary to identify new moths and bugs we find each morning around our house!
One of our favorites is the pink/yellow Rosy Maple Moth.
We found a rather large one yesterday and withing a few minutes of putting her into one of our bug houses, she began to lay eggs! Now 24 hours later she’s still working and is up to about 30 tiny yellow eggs on the walls of the habitat.
So our question is about what to do witht the eggs? Should we release Rosy after she’s done laying all of them?
If we leave the eggs alone in the bug house, will they hatch?
I’m assuming it might be too much to try and feed the larvae/catpillars for so long, so what kind of tree should we release them on after they hatch (if we’re so lucky)?
Thanks fo your help!

Rosy Maple Moth lays eggs

Dear Mo & Slyler,
Your letter contains so many wonderful questions.  You should not try to move the eggs because you may damage them.  Releasing the female moth after laying eggs will probably not matter since she will soon die.  Rosy Maple Moths, Dryocamps rubicunda, are members of the family Saturniidae, the Giant Silkmoths and Royal Moths, and they do not feed as adults since they have atrophied mouth parts.  Releasing her soon will allow her to continue to lay eggs near a proper food source for the caterpillars.  The eggs should hatch, provided the female mated.  If she was captured before mating, the eggs will not be viable.  The caterpillars should grow quickly.  To provide a learning experience, you can release most of the caterpillars, and try raising just a few.  The caterpillars will feed on the leaves of maple and oak trees.  If the name of a plant is incorporated into the common or scientific name for an insect, it is inevitable that the plant is part of the insect’s diet.

Hi Daniel:
Thanks for such a quick response!  I figured maple leaves might be as obvious as it is, but I wanted to be sure.   We’ll be keeping our fingers crossed the eggs are fertilized!

Blister Beetle

Dear boxav8r,
The distinctive coloration identifies this beetle as Lytta sayi, one of the Blister Beetles without a common name,  though some texts may refer to it as Say’s Blister Beetle.  According to Bugguide, it is found in the Northeastern portions of North America.

Great answer! And fast!  Thank you. Pete
