Baron Butterfly Chrysalis

Dear Ayush,
This is such a geometrically angular butterfly chrysalis, that we were very excited to attempt to identify it.  Thanks so much for indicating the food plant is mango, because we quickly identified this Baron Butterfly chrysalis, 
Euthalia aconthea, thanks to Alamy.  According to Daily Mail:  “The species is common in Singapore and is usually found on mango tree leaves and is sometimes considered a pest. Eventually, the caterpillar metamorphosizes into a butterfly, via a green, leaf-like chrysalis.”  According to Butterflies of Singapore:  “Eight days later, the pupa becomes considerably darkened, especially in the wing case area, signaling the end of the development of the adult still encased within. The next day, the adult butterfly emerges.”

Hickory Horned Devil

Dear Aaron,
Despite its fierce appearance, the Hickory Horned Devil is perfectly harmless.  This individual has grown to its maximum size, so it left the hickory, walnut or other food tree and it is searching for a suitable place to dig beneath the surface of the ground to pupate.

I found this bug sitting on the ceiling of our livingroom… I cupped I and brought it outside. After I took pictures, it crawled quickly out of the cup and flew away. It looked very similar to a lady bug. Is it similar? Can you tell what it is?

Eucalyptus Leaf Beetle

Dear Kelley,
This looks to us like a Eucalyptus Leaf Beetle,
Chrysophtharta m-fuscum, a species we learned to identify when we found some munching on the eucalyptus tree around the corner from our Mount Washington offices.  According to the Center for Invasive Species Research:  “Eucalyptus leaf beetle is a new pest of ornamental eucalyptus and was introduced from Australia into southern California around 2003. It is not controlled by native parasites or predators. In Australia it is commonly known as one of the eucalyptus tortoise beetle species.”

I’ve seen a couple of these bugs. They are pretty small, only looking like a tiny piece of bark that fell onto the flower. They seem to park themselves on the aster and aren’t afraid of being photographed. Today, I got a shot of one sucking on the abdomen of a small bee. It looked like the bee wad dead.

Ambush Bug eats Flower Fly

Dear Teddy,
Your images are exquisite.  The predator in your images is an Ambush Bug, and though it resembles a bee, the prey is actually a Flower Fly or Hover Fly in the family SyrphidaeAmbush Bugs are frequently found on blossoms where they ambush insects, many of which are pollinators.

Ambush Bug

Thanks for the “exquisite” comment, and the quick reply!!
My thought was that the prey was something like a Mason Bee, but of course, you’re right about the Flower Fly.
I have quite a few insect photos on my Flickr page:
And on Facebook:
Other than bees, my favorite insects to photograph are spiders, but I don’t get much love for my spider photos!
Thanks again!!!

Western Conifer Seed Bug

Dear Deb,
Though it is a North American species, one can make the argument that the Western Conifer Seed Bug is an invasive species when it is found outside its original range of the Pacific Northwest.  Beginning in the 1960s, there was a noticeable range expansion across much of North America and eventually into Europe, and this range expansion is probably due to human assistance.  Western Conifer Seed Bugs will enter homes when the weather begins to cool, and they probably stowed away in luggage and other items that people took with them when they traveled or relocated.  Though Western Conifer Seed Bugs feed on the seeds of conifers, there is no evidence they harm the trees themselves.

Thanks Daniel,     Cannot believe how many are crawling on my house, trying to get in. Some actually do and eventually die.  Is there any correlation between the enormous number of pine cones this fall and the appearance of theses Conifer Seed Bugs ?
Thanks again !
Hello again Deb,
Your observation that there is a greater food supply in the form of pine cones is a likely reason there are greater numbers of Western Conifer Seed Bugs this year.

Firefly Larva

Dear Robert,
This is the larva of a Firefly and many larval Fireflies are also capable of bioluminescence.  There is a similar image of a Firefly larva on the University of Kentucky Entomology site.

Thank you so much! Never dreamed that a firefly larva would look like this. Looked more like some type of roly poly spiecis.
