Two neat creatures collected from the Split Oak Forest bioblitzes: an aquatic bee and a subterranean grasshopper!

Technically a pygmy mole cricket (Orthoptera: Tridactylidae) in (or near) the species Neotridactylus archboldi Deyrup & Eisner, these beasts spend most of their lives in subterranean burrows in dry sandy habitats, feeding on the layer of algae in the soil crusts a few millimetres below ground.  They do come to the surface during the wet season after rains. For more info see Deyrup 2005

We collected this specimen in a pan trap in sandhill habitat at the fall 2018 bioblitz.  This is noteworthy because these flightless orthopterans have until recently only been known from a few sites on the Lake Wales Ridge.  This specimen represents a disjunct and probably genetically distinct population.

Perdita floridensis is a mining bee (Hymenoptera: Andrenidae) found in the Southeast that is only out as an adult for about a month in mid-spring. As a juvenile it lives in nests in the sand below seasonal ponds where it is completely submerged under water for several months.  To cope with this inundation, females coat pollen pellets in a water repellent substance when stocking their nests for their young, and larvae also secrete a water-repellent substance. For more info see Krombein et al. 2003

We collected this specimen in a Malaise trap in pine flatwoods habitat during the spring 2018 bioblitz.

UCFC during the pandemic

UCF employees must work remotely in these crazy times, so fortunately we have a large backlog of trap samples from surveys, bioblitzes and ecological projects to sort through, and then pin, label and database the specimens.  There are also many specimens to identify – doing so often leads us to finding new distributions, natural history, and even undescribed species. The current Bug Closet techs (pictured: Alessandra, Vikki, Rachel, and Dylan) are well-trained and experienced, and so reliably able to take their work home with them.

Cool finding by our tech, Brian Silverman

Bilateral gynandromorphy is a condition in which an organism develops the sexual characteristics of both sexes. This typically occurs as an early female zygote loses an X chromosome during mitotic division. The portion that remains XX develops female characteristics while the portion that is now XO develops male characteristics (Le & Rizk, 2012). This occurs in arthropods and occasionally in birds as well. This European Earwig (Forficula auricularia Linnaeus) was found in Stanislaus County, California. The “male” portion of the forceps is large and curved while the “female” portion is short and straight.
