Canoe River power line cut; Greeley pond   Leave a comment

Wow, ended up with so many photos. Will be working on identifying them over the next many days, if you’re interested in the actual IDs please come back and check soon!


Bombus: bumble bee

Sweat bee, Halictidae. Halictus ligatus?

Looks to me like Ceratina, Carpenter bees. For Massachusetts in June, all I see in BugGuide are subgenus Zadontomerus.


I haven’t been able to convince myself of any of the possible choices for this one. Maybe, just maybe, Lasioglossum? I’m not too sanguine about that.

Hylaeus modestus? In Colletidae.

Eumeninae (potter and mason wasps). Parancistrocerus cf perennis? Euodynerus cf hidalgo? My guess is the first.

Halictidae. I think Augochlorella cf aurata. But who am I kidding, I have no idea how to rule out Augochlora.

What the hell is going on here??? The first two photos show a fairly normal hymenopteran, but the third…!

It’s giving me sawfly vibes, but I really can’t say for sure.

What is going on here??

Ceraphronidae? Cynipidae (such as oak gall wasp)? The size and shape of the head and eyes are a little unusual, to me.

The eyes and head say Chalcididae to me. Look forward to finding out what it actually is. The hind legs look nothing like what I’ve seen in other Chalcid wasp photos, though. Will it actually turn out to be a Crabronid???

Maybe Chrysididae? Such as Holopyga or Hedychrum?


Grasshopper nymph. Takes a wiser man than me to figure out what kind it is from a photo at this age.


Small milkweed bug, Lygaeus kalmii, in Lygaeidae.


Pachygronthidae –> Seed bug, Phlegyas abbreviatus

I’m not even sure if it’s a planthopper or a leafhopper. Derbid planthopper, Cedusa cf maculata (compare Leafhopper, Agallia quadripunctata?



Agrilus ruficollis, red-necked cane borer, Buprestidae. Don’t see a Norfolk county, Massachusetts report of this, but they’re not rare.

Cryptorhopalum triste in Dermestidae, were all over the place on the flowers.

Bad angle. Carabidae? Something like Stenolophus cf ochropezus? Agonum albicrus looks better. Amphasia seems to have rufous legs/antennae. Apristus looks similar-ish. I should stop now.

Elateridae. I do not dare go any further.

Cantharidae –> Rhagonycha?

Mordellidae, tumbling beetles. Looks like Mordella marginata.


Excited to catch them flying!

Syrphid fly, looks like Sphaerophoria


Cesonia bilineata in Gnaphosidae


Beautiful mite! Similar mites in BugGuide were not classified any finer than “mites and ticks” in Acari.

Thomisidae. Xysticus? Xysticus vs Bassaniana is tough.

Asagena americana in Theridiidae.

Opiliones, aka Harvestman. Leiobunum vittatum, I think.

No arthropods!

Wasp and Jumping Spider   Leave a comment

I haven’t been able to go out for a while. But I work from home near the porch, giving the insects the opportunity to drop by and distract me.

This wasp, I think, is Vespula vidua (the widow yellowjacket). That means there’s a yellowjacket nest near by. I’m fine with that — they are genuinely fascinating.

Then there’s this girl. I’ve seen her regularly when I step out onto the porch. She’s a Platycryptus undatus and I’ve named her Grizzlee. Not sure why the white balance got so red, by the way.

Canoe River, Foxboro   3 comments

Walking along the powerline cut near Canoe River, Foxboro. Fantastic day for insects and spiders!

First, Diptera:

Conopidae, perhaps Myopa sp.

Lauxania in Lauxaniidae:

“Unmarked wings with very simple veination pretty much rules out Anisopodidae. Sciaroidea, I’d say, but not Mycetophilidae; Cecidomyiidae would be my guess, but it’s truly a guess.”



An ant alate?

Halictidae. Maybe Lasioglossum (subgenus Dialictus)? Don’t really know how to distinguish from Augochlora.

Pompilidae, Priocnemis minorata seems to be the only one registered in Massachusetts in May.

Another Lasioglossum?

Another Priocnemis minorata?

Looks like Sphecodes:

I caught a Sphecodes in flight!


I really don’t know how to tell Augochlorini from Lasioglossum.



Dermestidae: Cryptorhopalum cf triste

Cerambicidae! (I initially thought Staphylinidae). Molorchus bimaculatus.

Cryptorhopalum cf triste again

Chrysomelidae: Sumitrosis inaequalis

I spent a lot of time trying to see who was digging this whole but she never came out so it’s a mystery!

EDIT: Lytta sp. in Meloidae


Isthmocoris piceus actually looks like a better fit, in Geocoridae. I first thought it was Salda in Saldidae. Compare with

Zelus luridus nymph, always charismatic.


My first Thrips!!! But couldn’t find a good match. Aeolothrips, if I was forced to guess.



Pelegrina proterva.

A special place in my heart for Leucauge venusta!

Trying to capture the beautiful color of the chelicerae, but it didn’t come out right in the photos.

Borderland State Park   2 comments

First bug walk of the season (as opposed to the vernal pool and the wetlands). I spent a lot of time (too much time) creating many, many candidate flash diffusers. Today was the first actual trial.

Plenty of insects and spiders!


My guess: Hexomyza schineri in Agromyzidae. However, I’m told that it could plausibly be many others that are acalypterate.



Who is this? I was about to call it Bibio longipes — and then discovered that that is found only in fall. Maybe something like Bibio femoratus?

Anthomyidae, cf Anthomyia.

Another Bibio cf femorata?

Such a striking fly, probably Agromyzidae.

Male Bibionidae?


A mutillid wasp. Pseudomethoca simillima?

Cynipid wasp

Nomada luteoloides?

Probably Andrena.


The requisite six spotted green tiger beetle:

Notiophilus cf biguttatus

False blister beetle, Asclera ruficollis, in Oedemeridae? Or Podabrus punctatus? I *think* it’s Asclera ruficollis. But Pedilus lugubris is another possibility. Okay, now I’m going with Pedilus lugubris.

EDIT: according to BugGuide, Silinae in Cantharidae is the best starting point.

“Anthonomus, I believe, either A. suturalis or A. musculus.”

Elateridae. Maybe Dolerosomus silaceus?

Tarpela micans. For some reason, I only seem to see dead ones.


This beautiful Lycosid. Pardosa sp.

Naphrys pulex. Except that it might be a Pseudeuophrys erratica, which I’m just learning about — introduced from Europe. Or Habronatus?

Thanatus, in Philodromidae.

Solsticus insularis? Haplodrassus cf hiemalis? Callilepis pluto? Urozelotes isn’t confirmed in BugGuide near here, but I’ve seen it suggested ( for Massachusetts, so maybe this is that?

EDIT: Zelotinae looks good, but classifying any finer is highly questionable.

Opiliones (aka Harvestman):

Some scenery:

Moose Hill boardwalk   Leave a comment

Second foray with the new Laowa 24mm macro probe lens, using its ability to explore underwater. Instead of a vernal pool, focused on the area around the boardwalk. It becomes a swamp or a pool during spring melt, but does dry up at other times of the year.

The inside of a skunk cabbage that had been submerged by the spring melt:

Is this spirogyra?

Mosquito larva:

This beetle (which looks BB8 from Star Wars) is Desmopachria, in the tribe Hyphydrini, subfamily Hydroporinae, family Dytiscidae. I’m excited because it’s the first BugGuide report of this tribe and genus in Massachusetts — my third taxon that I have a state first (Dolichurus and Podium luctuosum are the two others).

I think this spider is Erigoninae, in Linyphiidae. It had fallen in the water, but managed to successfully get out. Going down to genus or species is very difficult, but Walckenaeria communis is a good fit, for whatever that’s worth. For example, compare with

The abdomen looks shiny from that angle, but in this photo you can see the hairs:

So many tiny springtails all over the place. It turns out that these are Sminthurides malmgreni, and that makes it the first report in BugGuide/iNat of this species anywhere in the USA. There’s another report in British Columbia, though. Combined with the Desmopachria (see below), that makes my fourth taxon that’s a first for Massachusetts.

Water mite, Hydrachnidia, with a springtail photo-bombing, as springtails do.

I saw a cluster of debris, that seemed to move when there was no current. Hmm. Then I saw another one, and another. After the fourth or fifth, it finally dawned on me that I was seeing caddisfly larvae. I’m not always the sharpest guy around.

They’re gorgeous and fascinating!

Here you can see the caddisfly larva emerging from the casing:

Water skimmer. Gerris sp? Need to rule out Aquarius cf remigis.

BugGuide: “Gerris: connexival spines not prominent, metatibia <3.3 as long as metatarsomere 1″. Whatever that means!

“Aquarius: hind tibia at least 4 times as long as metatarsomere 1; connexival spines prominent; pronotum dull; antennomere 1 more than 0.9 as long as antennomeres 2+3; adults winged or wingless”

Underwater plant, smooth and silky.

Salamander eggs. Note the gel completely surrounding the egg mass. Probably Ambystoma genus, Spotted Salamander egg clutch. Note that Jefferson salamanders do not come this far East, and blue-spotted salamander egg clutches are not this big.

A water beetle with distinctive markings. Haliplus, in Haliplidae (crawling water beetles).

another view, more of the dorsal pattern:

I’m including this information here, so I can search for it later. How to distinguish Gladicosa gulosa from Schizocosa:

This species in the particular is tough to distinguish from Schizocosa, but generally speaking, the stripe on the prosoma fans out slightly right around the eyes of Schizocosa. In Gladicosa, the PLEs visibly “cinch” the stripe in.
To illustrate:

Also: “You’ll also notice the overall shape of the prosoma in Schizocosa is rounder.”

Moose Hill vernal pool   Leave a comment

I don’t think I’m a big gadget guy, but I recently bought the rather extraordinary Laowa 24 mm probe lens.  This macro lens also happens to be waterproof, and allows me to sit on the edge of a vernal pond, dip the end of the probe into the water, and record what I see.

The single vernal pool had already dried up and split into multiple pools.  For some reason, one of them was utterly packed with Fairy Shrimp, while the other didn’t seem to have any.  It may be relevant that the one that *didn’t* have fairy shrimp, had plenty of frogs!

This photo gives you a good idea of how closely the fairy shrimp were packed:

Some more photos of their unearthly beauty:

Not a very good photo of a beautiful spider, Pirata in Lycosidae (wolf spiders), walking on water:

A friend has a copy of TopazAI denoise software, which uses AI to deblur. This is the output, so much better! Note that the foreground is improved without the background getting worse.

Bright red water mites (Hydrachnidia) were everywhere:

Look at the feathery legs!

According to BugGuide: “I think this is most likely Helochares maculicollis, but the angle isn’t great, so Hydrobius fuscipes and Cymbiodyta bifidus are possibilities”

Probably a water beetle larvae, probably Dytiscidae.

Phantom midge larva, I think, but I don’t have the expertise to rule out mosquito larva.

I have no idea what’s going on with this fly. Is it two flies mating? Doesn’t seem so from other angles. (EDIT: Ochthera tuberculata, in Ephydridae).

Mayfly larva?

Is this a Copepod?

I think this is an Ostracod:

Another Ostracod, I think:

The 24mm lens allows us to get into the creature’s world, rather than just photograph them. I think this is a wood frog, Lithobates sylvaticus:

Ice and leaf. The ice will melt, the leaf is dead, but they’re going out so elegantly, and the new will begin again soon.

Massapoag Trail   Leave a comment

Snowy day. Didn’t feel like driving, so explored a part of the Massapoag Trail I really should have spent more time in until now, from Lake Massapoag onwards.

Low light, and the nature of snowy woods, means that a lot of the photos worked best in black and white.
