We were thrilled to see this immature California Mantis,
Stagmomantis californicus, crawling up the screen door, moving toward the porch light where the moths were circling.  We love our first Mantis sighting each year, and the porch light is often a lure because of the bounty of food.  This morning, the little guy was perched on the picture window.

Found this crawling on my computer screen today. I had a window open, but still, not sure how It got in the house. I thought he might be a Praying Mantis, but the eyes have me baffled. Anyone know what this is?
Whatever it is, it’s in my garden now. He looked like a predator, so I wanted to give him a chance to do what he was made for. :)

Spiny Assassin Bug Nymph

Spiny Assassin Bug Nymph

Dear Kyrus,
This is an immature Assassin Bug, and though they are not related to Mantids, they share the physical feature of raptoreal front legs.  We believe your nymph is a Spiny Assassin Bug in the genus
Sinea, and you can compare your image to this image on BugGuide.

Hi, I found lots of these climbing on my apple tree. There was also a type of white fungus around which some of them congregated – this possibly contains eggs?
I don’t know if they are bad for the tree or not. They measure approx. 1cm, but some are slightly smaller. They have 6 legs but the back part of their body looks like a caterpillar.
I hope you can help.

Lady Beetle Larvae eat Hemipterans

Lady Beetle Larvae eat Hemipterans

Dear Barbara,
While there is a pest problem on your apple tree, nature seems to be controlling the situation.  What you have mistaken for fungus or eggs is actually a type of Hemipteran, possibly a Woolly Aphid which you can read about on the Royal Horticultural Society site.  The crawling insects are the larvae of Lady Beetles, and they are feeding on the Hemipterans.   The bad news here is that the Lady Beetle Larva is an Asian Lady Beetle Larva, a nonnative species, and it is believed that the proliferation of nonnative Asian Lady Beetles in North America is contributing to the decline in numbers of native species.

Hi Daniel,
I found this very interesting fly in my garden yesterday and I have been completely unsuccessful in finding an ID for it. Hoping you can help. One thing that was interesting was that it had a thick line of “feathering” on its hind leg. I’ve cropped these photos so that you can see the detail.
Hope you can help!

Feather Legged Fly

Feather Legged Fly

Hi Deborah,
Your Feather Legged Fly has some noticeable differences when compared to the images on BugGuide of
Trichopoda pennipes, but we are still relatively confident in that as the identification.  The BugGuide description is:  “Bright orange abdomen, velvety black head and thorax, and a fringe of short black hairs on the hind legs. Male: ferrugineous spot in the wing, abdomen dark orange at apex; female: wing evenly dusky, abdominal tip black.”  The biggest difference is the black abdomen on your individual, which just may be an example of variation within the species.  Your side view clearly shows the feathered hind legs.  This Feather Legged Fly is an important biological control agent, and BugGuide lists the hosts as:  “various pentatomorph bugs (Coreidae, Largidae, Pentatomidae, Scutelleridae) …  Anasa tristis is an important common host.”

Udate:  In looking through our own archives, this might be Trichopoda lanipes.

Thank you, Daniel!  That does look like my fly!  As always, I appreciate your assistance.

Found this rather Docile, Giant bee like bug today at my camp and could not identify.
About the length of my index finger (3″).
Much larger than a carpenter bee and someone thought it could be an invasive Asian Resin bee, but all pics look again, too small.
Both pics are the same bug.
Help!!
And thanks!

Bee-Like Robber Fly

Bee-Like Robber Fly

Dear James,
Your confusion is understandable.  This is a Bee-Like Robber Fly in the genus
Laphria, most likely either Laphria virginica or Laphria flavicollis.  Of Laphria virginica, BugGuide states:  “Easy to confuse with L. flavicollis. The main gestalt things to look for are the hairiness of the black abdomen, very fuzzy in virginica but somewhat glossy in flavicollis. The golden hair on the top of the thorax looks more swept back and finely constructed in flavicollis. And in virginica, the legs have a reddish brown tone to the fuzz in good light.”

Found this fellow under a moist hanging flower basket that I had set in the shade. Beautiful large black sheened beetle with two distinct blue spots. Should have measured but over an inch I’d say. Can’t find him on the web.

Caterpillar Hunter:

European Ground Beetle

Dear Michelle,
Your European Ground Beetle,
Carabus nemoralis, is quite beautiful, and we can’t quite bring ourselves to consider it an Invasive Exotic species, though we speculate it might be displacing related species that are native and that occupy the same niche on the food chain, and they might also be eating caterpillars of endangered species, but on the flip side of the coin, they may be contributing to the diets of insectivores or all phyla.
