Army ants (Eciton mexicanum) are specialist predators of other ants. Here, a group of workers take down a Neoponera huntress ant in an Ecuadorian cloud forest.

The elephant mosquito (Toxorhynchites rutilus) is one of the largest mosquitoes in North America with a wingspan of 12mm! They also do not bite, as females do not use blood for their eggs. They're also predators of disease-causing mosquitoes like those in the genus Aedes. So, friends! #invertefest

It is unacceptable for a world-class city like ours to allow its major natural history museum to close. We cannot allow it. My statement ⬇️
The text of Senator Saval's statement on the closure of the Academy of Natural Sciences museum. The words are in white on a blue background. Senator Saval's image is in the lower-right corner.

"For nearly two centuries, the museum of the The Academy of Natural Sciences has been the physical embodiment of a commitment to public natural history education. I was outraged to learn of the plans for its closure, both as a long-standing member of the museum and as an elected representative committed to the health and vitality of Philadelphia. It is unacceptable for a world-class city like ours to allow its major natural history museum to close.  

The mismanagement of such a treasured asset is a profound insult to the residents of the city and to the incomparable workers and curators at the museum. We cannot allow it."  The text of Senator Saval's statement on the closure of the Academy of Natural Sciences museum. The words are in white on a blue background. 

"This museum is a place where generation after generation first became enthralled with our world, and as we face the enormity of the climate crisis and an unprecedented loss of biodiversity, the continuation of the museum’s legacy of marvel and care for the natural world has never been more urgent. Partners from all levels of government must unite in our efforts to see this vital work continue."

Today was the first time I encountered the fascinating Oak Rough Bulletgall Wasp (Disholcaspis quercusmamma). Small females are developing inside the gall. The galls are exuding honeydew, attractive to yellow jackets and ants, who might protect the gall from parasitic wasps. #invertefest
Round and nipple shaped greenish brown galls being attended by Yellowjackets and paper wasps. Inside the gall is a developing female solitary wasp. When she emerges this fall, she will lay an egg in a dormant leaf bud.

If anyone is already planning their garden for next year, order some Dr. Martin lima beans. Incredibly productive vines with massive pods that are easy to shell. They are also super tender and flavorful. Named for the Philadelphia dentist who developed it in the 1920s. #gardening #legumes #beans
