Abstract To obtain information of Periplaneta americana, we analyzed the distribution characteristics of microsatellite sequences in the P. americana transcriptome (229 MB) by using MSDBv2.4. The total number of perfect microsatellite sequences was 38 082 and covered about 0.3% of P. americana transcriptome. The cumulative length of microsatellites was 618 138 bp, and the density of microsatellites was 2978.54 bp/Mb. In the different repeat types of the microsatellites, the number of the mononucleotide repeats was 20 002 (accounting for 52.52%), which obviously was the most abundant type. While the trinucleotide, tetranucleotide, dinucleotide, pentanucleotide and hexanucleotide repeats accounted for 24.51, 12.97, 8.13, 1.61 and 0.26%, respectively. The kind of different repeat copy categories in each repeat type was also quite different, such as the A in mononucleotide repeat type, the AG in dinucleotide, the AAT in trinucleotide, AAAT in tetranucleotide, the AAGAA in pentanucleotide, and the CAGTAG in hexanucleotide were the most of each category. The A, T, AC, AG, AT, GT, AAG, AAT, ATC, ATG, ATT, CTT, AAAG and AAAT were the dominant repeat copy categories, the total number of all these types was 29 933, accounting for 78.6% in the total number of microsatellite sequences. These results based on a foundation for developing high polymorphic microsatellites to research the functional genomics, population genetic structure and genetic diversity of P. americana.

The Fallen Titan

On one of my recent nature walks I came across the deceased body of an adult Periplaneta americana. They are remarkably large. Compared to all the other insects in the city only the praying mantises beat them. (and the mantises never leave lush gardens, so they rule the streets... did you know the roach & praying mantis are close cousins?)

I thought "that is your real crime you are too large & successful, too swift and athletic you can climb, leap, fly, survive... and we hate you for that."

No ants had come to collect this dead body, so I shuddered thinking of the poison that probably laced it. But the roaches in NYC can make it to adulthood and reproduce before our best death potions kill them.

We really need a different plan. I'm still not a fan, or very sympathetic, but boy oh boy do we kill a lot of more interesting and helpful creatures in a failed bid to slay the roach.

He was dead but I know he'll have a thousand children.

Can't even be ant food. Great job everyone!

had a full on falling-apart of my brain at 4am, trying to muster the will and plan how to contain a roach (American),

so naturally as soon as i wake up i read the creature's full wikipedia page.

#i succeeded in containment #but i had to leave him under a cup on the floor #i had to go to sleep #the task sapped all my energy #now he's just over there #under the cup #and i'm so afraid of him for no reason! #it's the wings actually mostly #cockroach #american cockroach #roach #Periplaneta americana #why do they have to have wings #he was just minding his business exploring my bathroom #being entirely harmless #poor guy spent the night under a cup #phobia #roach phobia

Scurry

In the orange-tinted dark I scurry over the ground near the gray forest. Thousands of scents on my antenna and all of them could be food. A great mass shifts in the distance. A high pitched scream sounds. Then the forest lifts up next to me. I scurry faster, faster, faster, until suddenly the forest comes down sideways, and I can scurry no longer.

cockroaches have always been a group I hold in high esteem among the insects, and I saw a lot of nice ones in Singapore & Malaysia this past summer.

first is the tiny Pseudophyllodromia laticeps, whose name means ‘broad-headed’ but really most of its head are huge eyes! unlike the rest of these cockroaches, which are nocturnal, these flit around in daylight like houseflies and are just as quick to take flight when approached.

I’m not fully sure what these next two are, perhaps blatellids.

Allacta is another pseudophyllodromiid and a very charming one, with delicate white markings on a shiny black background.

epilamprines are a lovely group of blaberid cockroaches that are diverse in the area; these three were Rhabdoblatta of three different species. the last one there was probably the prettiest roach I saw on the trip; sadly it was found dead on the path.

Pseudophorapsis nebulosa is a big epilamprine that tucks away its appendages and resembles a dead leaf during the day.

I’m not sure what these next two were, possibly more blaberids?

a male Pycnoscelus indicus was a nice sight—while very common, I’m only used to seeing female Pycnoscelus surinamensis, which descends directly from that species! several lineages of P. indicus independently developed the ability to clone themselves instead of mating; these female-only strains are together known as P. surinamensis.

the roach on the right is Ergaula pilosa, a cute burrowing cockroach (Corydiidae).

these two nonnative species need no introduction: Periplaneta australasiae and Periplaneta americana (Blattidae), two species that are big “pest” roaches worldwide. these two were just chilling in the forest, however.

blattids are a funny group since one bunch are all “pest roach-y” (the blattines above) but the rest are strictly outdoor species ranging from wildly colorful Australian forms to bumpy, ornate archiblattines like this Catara rugosicollis. I missed getting photos of another lovely species, Protagonista pertristis, which sprayed my hands with an eye-wateringly-powerful scent of oranges before making her escape into the leaf litter.

Weird Wasp....Tuesday?

I was getting kind of down in the dumps about not having any ideas for comics for a while, but I just had to find an excuse to draw an Evaniid today. The other two came into the picture afterward. Sometimes, it can be quite a challenge to come up with an idea or scenario that incorporates some kind of joke or pun related to certain insects, especially wasps.

I'm glad this one worked out. I suppose it would have made more sense to draw an ootheca in the picture, although I am curious about wether the ootheca "appears" externally after mating? I've seen photos of female Periplaneta americana without oothecae, either that, or I'm blind, lol. I welcome any advice or corrections!

The original accompanied caption:

When cockroaches are on the menu... Ampulex compressa and Evania appendigaster are both cockroach parasitoids. A. compressa is known for "zombifying" cockroaches, by stinging them in the brain and then dragging them into the wasp's burrow by the antennae. An egg is then laid on the host. E. appendigaster, aka Ensign wasps, parasitizes roach oothecae by laying eggs into the cockroach egg cases. They also distinctively have vivid blue eyes.

This will be an interesting match! Who will win!? 🤔 😆

(Also, if rock-paper-scissors doesn't require hyphens, I can easily remove them).

[dreamingofthesevenseas]

hey can i get those five species of cockroaches listed. i was gonna leave it at that but it seems you are a cockroach main so a top 5 list might be more interesting if possible

Omg thanks for asking me about roaches 🥺 and sorry for taking that long to answer your ask but I just couldn't throw a list without at least giving some information about those wonderful little creatures that are cockroaches! I absolutely love roaches, they are so smart, so interesting, so adorable (their eyes shaped like beans!!!).

5- American Cockroach (Periplaneta americana)

Of course, our iconic roach, maybe the first one that come into your mind when someone says "cockroach", is on the list.

American Cockroaches have one of the greatest capacity of adaptability in the entire animal kingdom (even if we wrongly think they can survive a nuclear explosion). For example, cockroaches loves sugar! But noticing that a lot of traps against them are made with sugar, they are changing their diet to eat less to not at all sweet food, to the point females will refuse to mate with a male who is often eating sugar. This is not specific to this species but I still wanted to tell (because that's pretty interesting).

Another amazing thing I wanted to talk about is how cockroaches manage to defend themselves against predators like the emerald wasps. They turn around and hit it with their rear paws, just like on the video ↓

4/ ember wood cockroach (Ectobius vittiventris)

This one is in my top 5 for emotional reasons 🥺. There are plenty of them in my garden so I can observe them and interact better with them than any other species of cockroaches. I played with one of them once.

Have you ever see a cockroach pooping? Because I do. One of this bad boi pooped on me once. I had a wood roach resting on my arm when suddenly it started walking around. When it stoped it bended its body and I was like "woah! Cockroaches can sit!?" Until I noticed a black dot....

3/ question mark cockroach (Therea Olegrandjeani)

Ok I'll be honest with you. I don't really have anything to say about them other than are very pretty...

But did you know the dots on its back only appear after the last moult? The juveniles are all dark brown before becoming adults.

https://youtu.be/Y1eiszrsWto?si=LiaGahUOEi63PQng

2/ Madagascar hissing cockroach (Gromphadorhina portentosa)

They are call like that because of the hissing sound they make to frighten predators since they are a wingless species.

The females of this species carry their ootheca (sort of bag with eggs in it some female cockroaches and mantis carry at the end of their abdomen) internally, making the eggs hatching inside the mother (this is called ovoviviparity). The nymphs stay close to their parents for protection and to be fed.

1/ Emerald Cockroach (Corydidarum magnifica)

Of course, the emerald cockroach would be the first on list! Look at them, they are beautiful! You can easily recognise the male from the female since he is the one who got wings. One thing I love about cockroaches is when the males and females look drastically different from each other.

Just like the hissing roach, this species too have its nymphs formed inside the mother for 4 to 6 months. Once born, they will hide under their mother to be fed and protected. Then, the nymphs will explore their environment while staying close to their parents, most of the time they will hide under the mother but it's not rare to see them hiding under males.

A Dumb Solatorobo Headcanon...

!Spoilers for Solatorobo Part 2!

Also content warning for a mention of bugs ewwww...

Imagine when Red and the gang get to earth, they find these little bugs crawling all over the place. Yurlungur tells them that they are "Periplaneta Americana"

Red: "Peripla- What now?"

Yurlungur: "American cockroaches"

Yes, even after a world ending war with giant mechas built with alien tech, the cockroaches ARE STILL ALIVE. Elh is very much not happy with this bit of info. At least they're nowhere near as big as the insects in Shepard, but...

Elh: "tiny bugs are still bugs."

Well said lol
