The Coyote Melon is a squash plant that has taken root in the meadow near the big dead walnut tree, and it is beginning to set fruit.  This sprawling plant is a native and it can be found wild on the hill on a winding hairpin curve above La Abeja restaurant on the East Side of Mt Washington in the Greater Cypress Park Neighborhood.

Coyote Melon Plant

We expect native bees are pollinating the blossoms and perhaps getting trapped inside when the blossoms close.

Update:  September 25, 2011
Due to a very low turnout of volunteers and the absence of one of the cohosts, the work party ended a bit early today after plants in the nursery were watered and some Castor Beans and Poison Hemlock were pulled out.

What's That Bug? does not endorse extermination

Metallic Sweat Bee

Half wasp, half bee
Location: Phoenix, AZ
August 27, 2011 10:04 am
So I look up, and there are 20 of these in my kitchen. I’m in Phoenix, AZ, its August, they can fit on my pinky nail, very small, iridescent green thorax and head, abdomen is striped black and yellow like a bee. Its hard to tell if its a wasp or a bee, but the morphology tells me bee. Any info would be appreciated, Thanks!

Hi,
Here’s a small fly that I pulled out of the bird bath last week. The photo isn’t great, but I’m hoping it’s good enough for you to be able to identify.

Yellow Masked Bee

Hi Anna,
We realized when we first looked at this photo two days ago that it was a bee and not a fly, but we did not have an identification, so we did not write back.  We have now identified this little creature as a Yellow Masked Bee in the genus
Hylaeus, thanks to this photo posted to BugGuide.  According to BugGuide, there are over 50 species in North America, and we do not have the necessary skills to identify this individual beyond the genus level.

Many thanks for the id on this little bee.  Maybe one day I’ll finally stop mixing up my bees and flies.  I don’t have many bees that plunk themselves into the birdbath, and this was a very small one.  My eyes aren’t what they used to be!

Ensign Wasp and Unknown Bee on Curacao

need help identifying Bug and Bee
Location: Island of Curaçao in the Caribbean
August 19, 2011 7:08 pm
Hi, I am Garrick Marchena, from the island of Curaçao in the Caribbean and I need help identifying these two insects.
I know one of them is a bee, but i need to know what type of bee. Its certainly a type I’ve never seen or heard of before.
The other is an insect known to our island as one that brings luck. It is called ”Mamoendenge” by our local people, but i need to know the official name. It kinda looks like a Mud Dobber wasp but i don’t think it is. Its back part bobs up and down as it walks.
I really appreciate if you can help, but if you can’t maybe you might know someone who does?
thanks you very much,
wkr
Garrick Marchena.

Possibly Carpenter Bee

Hi Garrick,
Though we don’t recognize your bee, and we have been unable to locate a match online, we suspect it is some species of Carpenter Bee.  The other insect which you call Mameondenge we find very interesting because of the notion that it brings bad luck.  This is a beneficial Ensign Wasp, so named because of the bobbing of its abdomen which is thought to resemble a flag.  The Ensign Wasp parasitizes the oothica or egg cases of Cockroaches, helping to reduce their population.  We wonder if the name the locals have given it is a reference to dengue fever which is spread by mosquitoes.  You might want to educate the locals as to the importance the Ensign Wasp plays in Cockroach control.

Thanks for the fast response!!!
Locals say that the Esign Wasp (or Mamonedenge) brings GOOD luck actually! Sorri i wasn’t clear on that.
Now that i know this information I’m gonna love this bug even more!
From what I’ve searched on the internet the bee does look like a carpenters bee. Also seems to be a type of solitary type bee.
This is really awesome!
Let me know if you are going to use the pictures because i would like to add a copyright on them first if you don’t mind.
Thank you very much for your help.
Garrick.

Sorry Garrick,
We somehow inserted the word “bad” before luck in your letter.  The images are already posted live and we have cropped them, lightened them and formatted them to our site.  Your name is printed with your original email.

Metallic Sweat Bees

Saw two of these iridescent green bees yesterday. They burrowed in the soil below our fig tree and did lots of hovering in the vicinity. They were no more than 1/2” in length. One had pollen, the other didn’t. I’m guessing halictidae agapostemon texanus… but would love for the experts to weigh in. Thank you!

Hi Tracy,
We agree that you have photographed Metallic Sweat Bees in the family Halictidae, but we are very reluctant to agree to a species or even a genus identification of this confusing family. 
We are especially thrilled with your photo that shows a Metallic Sweat Bee digging.  According to BugGuide, the are:  “Typically ground-nesters, with nests formed in clay soil, sandy banks of streams, etc. Most species are polylectic (collecting pollen from a variety of unrelated plants)”

Leafcutter Bee Nest Relocation

leaf cutter tragedy
Location: western Washington
August 15, 2011 8:33 pm
This year I planted hanging buckets of tomatoes and peppers. One of the planter types turned out to be disasterous as they failed one, after the other. The last one, with pepper plants well along, exposed one dead bee and around ten little cigar tips. I recovered the plant, then scooped up the (mostly peat) filling and cases into a ceramic planter. Is there anything I can do to encouage the larva to continue?

Leafcutter Bee Nest Tragedy

Hi kimmiee,
We are sorry to hear about both the loss of your produce garden and the resulting tragedy of the Leafcutter Bee nest.  You have probably done all that you can do.  We would suggest keeping the peat and the nest in a sheltered location and ensuring that it does not dry out and desiccate the nest.  As long as the individual cells were not damaged, there is a chance the bee larvae might survive.  Even if your well intentioned intervention fails, we are awarding you a Bug Humanitarian Award for your valiant efforts.

Before I accept this award, I’d like to thank all the little bees……
For providing me with beautiful flowers, tasty fruits, a myriad of grains, and hours of enjoyment in my garden.
;-> Kim

We love short and sweet acceptance speeches.

gardening blog update:  August 18, 2011
In our opinion, peppers and tomatoes should not be planted in hanging baskets except for ornamental purposes.  Do not expect the kind of harvest you will get out of tomatoes planted in the ground in a favorable location.

“In our opinion, peppers and tomatoes should not be planted in hanging baskets except for ornamental purposes.  Do not expect the kind of harvest you will get out of tomatoes planted in the ground in a favorable location.”
Normally I would agree with you.  Living on the Western side of Northern Washington, it is often tricky, to get tomatoes to ripen.  This year was especially hard because unlike the rest of the country, we were very cool well into the middle of July.  So I’ve been pretty pleased that I am getting ripe tomatoes and, in fact, I’ve gotten two peppers off the plant that tried to suicide with the leaf cutters nest.  I stuffed it into an other (fabric) hanging pot and it has recovered better than I expected.  There are other pepper varieties in that planter, and while they have done fairly well vegitatively, I suspect I won’t get any peppers off them.  But, hope springs eternal, and if we get decent weather through October, there could be some.
The hanging planters have enabled me to place multiple plants in a small corner of the yard which achieves maximum sun exposure.  I’ve been religious about watering them solidly every day.

Kim's Hanging Tomato Plant

Thanks for the update Kim.  Watering a hanging basket would be an important factor in getting a yield out of plants.  We did not mean to imply that vegetables should not be grown in hanging baskets, just that planting in the ground will most likely give larger plants and a better harvest.  Did you get positive results with the Leafcutter Bee nest relocation?

Update:  August 31, 2011
All I can say regarding the nest is that some of the tubes are still intact.  I sort of assumed that they may not hatch (fledge? emerge?) until next spring, or at all.  The peat was disturbed right after I picked them up by the squirrels in the yard, and a couple of the tubes were ripped open but I’ve now inverted the bowl and propped it to provide both cover and ventilation…  It is in a brick planter, under an evergreen.  So, it’s not being dried out, and it doesn’t get enough direct light to bake… But I haven’t disturbed it since to inspect the tubes.  Maybe this weekend I’ll work up the courage to look and see if I can identify any changes….

Thanks for the update.  Let us know if there is any activity next spring.

Update:  September 9, 2011
I said I would look, so I did.  What I found was… not much.  It appears that most of the wonderful cigar tips were just gone, although I did see an occasional hint of a tube or the lacy leftovers of one of the cut pieces.  I also found the little beads you see in the picture.  Again, not knowing enough about the life cycle, I’m not sure at what I am looking.
I know in some of the the original tubes which were destroyed, there was a definite layering effect visible which I took to be piled up pollen with an egg or larva on top.  I should have attempted a picture of that.  These don’t seem to be the same, is it a pupa?
If so, I would surmise at least some of the original group are already out there pollinating again.

Is this related to the Leafcutter Bees?

Hi Kim,
We are not certain what your new photo depicts, but we will post the photo and try to do some research.  This might not even be related to the Bees.

Milkweed Meadow: Bumble Bee and Soft Winged Flower Beetles

Location:  Elyria Canyon State Park, Mt Washington, Los Angeles, California
August 13, 2011
WE keep returning to the Milkweed Meadow to document the progress there, and the Monarch Caterpillars have both vanished.  The Bumble Bee is usually there during the time the sun strikes the blooms, but we are still not certain if this is Crotch’s Bumble Bee or the California Bumble Bee.

  We also noticed numerous tiny beetles on the milkweed blossoms.

Alas, the old model digital camera we are using does not have a macro setting that will allow us to get closer.  We would like to identify these beetles.  After the fact, we had a terrible thought that they might be the Walnut Twig Beetles that are spreading the 1000 Cankers Diseaseto black walnuts in the western states.  This matter will take additional research.  Many beetles with wood boring larvae feed on pollen as adults.  We should return tomorrow morning and collect a few specimens to take to the Natural History Museum of Los Angeles County.

Daniel:
These are pretty easy to subfamily level.  They are soft-winged flower beetles in the family Melyridae, subfamily Dasytinae.  After that it gets really messy, really fast!  Nobody wants to try to ID them even to genus…..

Milkweed Meadow Continued: Which Bumble Bee is it?????

August 4, 2011
We walked back to the Milkweed Meadow in Elyria Canyon Park this morning to check on the status of the two Monarch Caterpillars,
Danaus plexippus, thinking that they might have transformed into chrysalides, but I could only find one of the caterpillars.  Hopefully the other was just elsewhere, or perhaps it found a nice place to metamorphose into a chrysalis

Monarch Caterpillar

A very wary Bumble Bee would not let me get close enough with the camera, and after several aborted attempts, we were lucky enough to get a few photos.  This is most definitely not a Yellow Faced Bumble Bee.  We were not able to get any photos of the abdominal markings until the last image.

california bumblebee 20110804 300x206 Milkweed Meadow Continued:  Which Bumble Bee is it?????

Crotch's or California Bumble Bee???

Just as it was flying off it showed its signature markings, but interestingly, it doesn’t match any of the images on BugGuide for the four species that Charles Hogue, in his landmark book Insects of the Los Angeles Basis, indicates are found locally.  After a bit more searching, we determined it might be Crotch’s Bumble Bee, Bombus crotchii, based on the illustration on the North American Bumble Bees and confirmed on the third photo down on the Las Pilitas Nursery webpage, and that appears to agree with this BugGuide image as well.  The Discover Life website also has photos.  Continued research is filling us with doubts.  It seems to match what we identified as a California Bumble Bee when we found one napping on the wisteria this spring.

There appeared to be more Large Milkweed Bugs today than on Sunday, and there were several places where the Milkweed Aphids, AKA Oleander Aphids, Aphis nerii, were quite plentiful.  Read more about Milkweed Aphids on BugGuide.

Milkweed Aphids

Before leaving, I made sure to pull some more Marestail or Horseweed, Conyza species (See Virginia Tech Weed Identification Guide or CalFlora) and more of that prickly yellow flower that is still not properly identified that might be a Spiny Sowthistle, Sonchus asper (See Virginia Tech Weed Identification Guide).

Update:  on the Bumble Bee identity
August 5, 2011
Now we aren’t certain if the Bumble Bee is a California Bumble Bee or a Crotch’s Bumble Bee.

Update:  August 7, 2011
I returned to the Milkweed Meadow in Elyria Canyon Park to search for the Monarch Chrysalis, but the only caterpillar I could find has still not metamorphosed.

Update:  August 11, 2011
I made a trip to the Milkweed Meadow in Elyria Canyon Park this evening about 6:30 and I was unable to find any Monarch Caterpillars.  I hope they wandered away from the milkweed to find a suitable location to transform into chrysalides.  I photographed a couple of Large Milkweed Bugs.

The new addition to the insects that have become part of the milkweed ecosystem are Small Milkweed Bugs.  I found them  on two different milkweed plants.

The individual I photographed was a difficult subject, and it kept hiding among the blossoms of the milkweed inflorescence.  I needed to intervene by including my hand in the photo to get a nice angle on the unwilling subject.
