Hello WTB,
This cicada killer startled me somewhat as I was out weeding the garden. I initially thought it had deposited a bit of trash. When I realized the ”trash” was an annual cicada, I dashed in to fetch the camera and thought you’d like to see the outcome.

Cicada Killer with Annual Cicada

Dear Takoma Park animal lover,
Wow, what a marvelous series of photos. 

Cicada Killer with food for her brood.

The female Cicada Killer is really a powerfully built wasp to drag and glide back to her burrow with a paralyzed Cicada for each egg she lays.

Subject: Beautiful bee or a blue tail fly?
Location: Auburn, NJ

This regal creature somehow managed to find it’s way into my kitchen, where I discovered it hanging on a coffee mug the other morning. I got the camera and managed one clear focused shot before I gave her a lift outside. In sunlight the tail end appeared almost a translucent green, which I’m sorry I can’t show.
I’ve been scanning here and at bug guide, but can’t even determine if I’m looking at a bee or a wasp or a fly? The antennae and eye shape suggest one thing, the body size another. Any clue you could offer? I don’t recall ever seeing another like it.

Cuckoo Wasp

Dear Creek Keeper,
This jewel-like creature is a Cuckoo Wasp in the family Chrysididae.  The females lay eggs in the nests of other hosts in the order Hymenoptera to which they also belong.  We suspect that each species of Cuckoo Wasp is very specific as to its host, though we are not sure if it is limited to species, genus or family.  We also have problems differentiating one Cuckoo Wasp from another at the species level, though they are quite distinctive as a family.  According to
BugGuide:  “Most species are external parasites of wasp and bee larvae; one subfamily (Cleptinae, one genus, Cleptes) attacks sawfly larvae, another subfamily (Amiseginae) the eggs of walkingsticks.”  BugGuide further clarifies:  “Some species are parasitoids and others cleptoparasites. Either way the host larva dies” and then further clarifies “Parasitoids feed on the larva of the host and cleptoparasites ‘steal’ the host’s food. The food-stealing behavior of cleptoparasite species resembles that of the cuckoo bird and gave rise to the cuckoo wasp’s name. Hosts of parasitoid species include bees, sphecid wasps, potter wasps, sawflies, silk moths, and the eggs of stick insects. Cleptoparasitic species feed on provisions of sphecid wasp nests, which may include dead spiders, true bugs, aphids, or thrips.”

Lesser Willow Sawfly Larvae

Hi ian,
These are Sawfly Larvae and we found a photo on FlickR that looks identical that identified them as Lesser Willow Sawfly Larvae,
Nematus pavidus.  We verified that ID on BioLib as well as on Naturespot UK.

Subject: mass of bugs on downed sycamore

I noticed masses of this bug on a sycamore that had been downed by a recent storm. This part of the tree was leaning, not on the ground. The tree is located in a park in woods near freshwater wetland.
I’ve included one photo with a bee to provide size comparison.

Giant Bark Aphids and Yellow Jacket

Hi Martha,
You have submitted photos of Giant Bark Aphids,
Longistigma caryae, and here is what we learned about them on BugGuide:  “This is the largest aphid in North America with adults averaging about 1/4 inch long. They also have long legs which makes them appear even larger. Males and some females are winged but egg laying females are wingless. They are brown with black markings (giving them somewhat of a mottled appearance) and have short, black cornicles. When alive they are often partially covered with a bluish white, waxy secretion.  BugGuide continues:  “Activity usually begins in late April in Oklahoma. An adult female gives birth to live young and a colony is formed on the underside of the branches of the host tree. Several generations occur during the summer and fall. Activity continues into mid-November in some years. Late in the fall females lay eggs in bark crevices or on the smooth bark of smaller limbs. The eggs are yellow when laid but later turn black. They are the overwintering stage.”  Sycamore is listed on BugGuideas a host plant and the complete list of host plants is:  “American elm, pin oak, live oak, post oak, blackjack oak, pecan, hickory, sycamore, and golden rain tree. Other trees which might be infested include maple, basswood, birch, beech, walnut, chestnut, and willow.”  We suspect the felled tree was oozing sap which attracted the Yellow Jacket.

Unknown Wasp

Hi Danielle,
We have been away from the office for three days and email requests have really piled up.  Identifying your wasp might take considerable research and we will have to return to that task.  The photo and creature are amazing looking and we want to post it as unidentified for now.  Hopefully one of our readers, who does not have several hundred emails to answer and make posts of the most interesting of them, can assist with the identification.

Karl identifies Nocturnal Paper Wasp
Hi Daniel and Danielle:
It looks like a Nocturnal Paper Wasp (Vespidae: Polistinae), probably in the genus Apoica.  As far as I can tell there are three species of Apoica in T&T (A. pallens, A. gelida and A. pallida). I am not sure which one this might be but it looks very similar to A. pallens, a species that occurs throughout much of Central and South America, and the Caribbean region.  Regards.  Karl

Thanks Karl,
As always, you are awesome and your contributions are greatly appreciated.

Dear Bugman,
What kind of bug is this?
Signature: ???

Thyreodon atricolor

Hi Chris,
This is a parasitic Ichneumon,
Thyreodon atricolor.  According to BugGuide:  “Although most members of the huge family Ichneumonidae are difficult to identify, this large species is an easily recognized, day active, slow flying parasitoid of sphinx moth caterpillars.”
