This little bug lives up to its name.

It is a big-eyed bug (Geocoris sp.) eating whiteflies. Even small predators often have big eyes as a way of finding prey.

After 257 Mystery Seed of the Week posts, it seemed like it was time for a change. But what to do next?
The answer was inspired by a book, Seed to Seed: The Secret Life of Plants by Nicholas Harberd.
Right in the first entry in the book, Harberd reveals that over the last few decades plant scientists have decided on a unifying method to help move the field of plant genetics forward more quickly. Instead of trying to examine a little of the genetics and development of many, many different plants, perhaps it would be more enlightening for everyone to study one plant thoroughly and assume that the other plants probably had the same or similar properties.
The plant they chose to investigate was thale-cress, Arabidopsis thaliana.

Why did they select this small weedy plant? Arabidopsis thaliana is the lab rat of the plant world. It is small and it self-pollinates, so it can be grown easily in the lab. It completes its life cycle quickly, producing flowers within approximately three weeks and seeds in about six weeks. In addition, thale-cress has a small genome that has been completely sequenced, so geneticists can build on what is already known.
Where does this unifying idea take us?
Rather than moving randomly from plant species to plant species as we have been doing with Seed of the Week up to now, let’s change gears. Following in Nicholas Harberd’s footsteps, let’s learn more about plant science by delving deeply into the secrets of a single type of plant over the next few months. Who knows what we might find out!
What do you think of this plan? Would you like to join in the journey? What questions about plants would you like to answer?
Arizona’s seasons are often out of sync, especially in the Sonoran Desert. When everyone else is shutting down and getting ready for fall and winter, our wildlife is gearing up. A few weeks ago, we featured some insect eggs. Now we have caterpillars and chrysalids galore.
Take this larva of a queen butterfly resting on a rush milkweed. It is taking advantage of the new growth the plants are putting out after recent rains.
Some of the faster developing larvae have already transformed into chrysalids. They will soon be adult queen butterflies.
The skipper butterflies have already reached adulthood and are ready to lay eggs again.
Check out this post by Margarethe Brummermann who says there were 28 species of butterflies (as well as other insects) in Madera Canyon this week. She also posted an amazing video on Flickr.
