Which of these arthropods is an ant?

Ant_Mimics_Quiz

Here is a video I did a while back on ant mimics. In the video I say that you can type “MIMIC” to recieve the free PDF; however, that only works on facebook. You can also download the PDF from here: Ant Mimic Bug Quiz Answers

So, how can you tell mimics apart from ants? Here is a list of characters you can use to tell if a critter is an ant:

  • Three pairs of legs (six legs total). Ants have six legs, while spiders have eight legs.
  • Ants have geniculate antennae (“kneed” antennae).
  • The second and/or third abdominal segment has a/have hump(s).

Why do other arthropods mimic ants?

Myrmecomorphy (a fancy word for “ant mimicry”) provides protection from a lot of predators or is a great way for predators to fool their ant prey. Therefore, the form of mimicry is either protective or aggressive. Most organisms do not want to eat ants (of course, there are some exceptions) because many (although not all) ants sting and/or bite, are aggressive, and/or taste bitter. In the case of a few predators, they have evolved to look and/or smell like their ant prey that they hunt. Ants are fierce, so being able to get close is an advantage to those organisms that want to eat them.

These are the ways in which organisms can mimic ants:

  • Smelling like an ant (Wasmannian mimicry)
  • Behaving like an ant (running around like one)
  • Visually looking like an ant (Batesian mimicry)

They are many examples of ant mimics! Many spiders, treehoppers, mantids, stick insects, katydids, etc. mimic ants. Happy hunting!

Don’t Get Choked Up Over It! Can Insects Choke?

Can you hatch eggs taken out of a female katydid?

This is a pretty cool question:

Hi,

I killed a large green grasshopper-like bug, only to find several reddish- brown rice-shaped things inside. Are they eggs? Can they still hatch?

I’m not sure what type of insect it was, but my best guess after an Internet search is… conehead/katydid.

Also, why might I find these insects in my home? Surely bright green bugs feed on vegetation?

Katydid Eggs

In this case, it sounds like a Katydid which got inside a house by accident. It’s common for bugs to get inside a house, and katydids just kind of keep looking for a way to get out when this happens. Here, the katydid was smashed and some eggs popped out…which led to the above question.

If you crush a bug, and eggs come out, they’re not going to hatch. The eggs need to be activated before they can develop, and taking the eggs out of the female without them being laid bypasses that process.

…but how are the eggs activated?

What, exactly, has to happen while the eggs being laid for them to start to hatch?

Help us out by taking a survey!

We’ve written about scientific conferences before, and we’re happy to announce that all of our writers will be together at ESA 2017 in Denver, Colorado!

As always, we’ll write a post summarizing our experience…but our talk is a bit different this year. We’d like some information on our audience for the talk.

Here’s a link to the survey, and we’ll post a short bit of information for further context below the fold.

Goop offers bug repellent at 6x what a comparable product would cost.

Written by Joe Ballenger

So…I was on Twitter, and this tweet came across my feed.

I’m familiar with GOOP and had a pretty good idea of what I was in for when I clicked the link…and I was actually happy to see that they were selling something that looked like it could be useful.

…and then I looked at the price and freaked out a bit.

GOOP

You should not be paying $30 for a bottle of bug spray.

Are there invasive insects from North America? The political consequences of our invasive species.

 

Written by Joe Ballenger

This question about invasive species caught my eye, mostly because I’m not sure I can give a complete response.

A lot of the insects I deal with are agricultural pests, and most of our agricultural pests have come from other parts of the world because of shipping activities. A lot of invasive species, however, have also come from America as well. Fall Armyworm, native to North and South America, has started cutting large and destructive swaths across Africa after it was introduced. Western Corn Rootworm, a billion-dollar pest, has been introduced to Europe and threatens agricultural supplies there as well.

Unfortunately, I’m just not familiar enough with this topic to give a super complete list…but I do want to talk about this topic because I want to highlight not only the economic ramifications but also the political ramifications that introduced species have. Instead of giving a complete list of North American introduced species, I’m going to focus on the one I believe to be the most important…not only economically but politically.

The pest species is the Colorado Potato Beetle, and it’s probably the best documented invasive species from North America. It’s expanded it’s population from Mexico, into North America, and has spread across the world over the past 150 years. It’s extremely hard to kill, and because of this, it’s played a prominent role in every major world conflict since WWI.
