Its quite rare that the tables are turned in the “anole eat insect” world. But in some cases, anoles instead find themselves becoming the prey.
A natural history note published September 2019 in the journal SAURIA details an unusual observation of anolivory by a Praying Mantis. Specifically, it discusses an event involving the predation of a sub-adult female Anolis (Norops) cusuco.
Anolis cusuco owes its name to its type locality in the cloud-forest of Cusuco National Park, Honduras, and is a species endemic to the country. Few publications exist regarding the natural history of this species and much regarding its ecology, including its potential predators, remain unknown. While a small contribution, this observation describes the first, albeit somewhat unsuspecting predator for Anolis cusuco.

Let’s be honest: anoles are fascinating! These charismatic and well-adapted lizards are always a pleasure to watch and document. Better yet, no matter how well you think you know a species, they’re still always full of surprises.
The sleeping behavior of anoline lizards is a fascinating aspect of their natural history, and a growing amount of literature has detailed species-specific sleeping activities. Typically, anoles are considered solitary sleepers owing to their territorial nature, but ‘behind closed doors,’ this may not always be the case!
For those curious, a recent ‘behavioral oddity’ published in Mesoamerican Herpetology by Brown & Arrivillaga (2018), reported an example of three individual Anolis (Norops) cusuco sleeping together on a perch! The individuals were so close that portions of their bodies overlapped! Strange, indeed; this observation contrasts the typical view of anole sleeping ecology, territoriality and indeed that what is known for this species (Clause & Brown, 2017). In over 5 years of visiting Cusuco NP (observing countless solitary sleeping A. cusuco), imagine the surprise in finding these anoles having a sneaky snuggle!!
As we wrote: “Although a conclusive explanation is not available, we suggest that because the sleeping group consisted of one male and two females, that the shared perch might have been breeding-related. This situation might be associated with the overlap of male and female territories, or by the anoles awakening close to necessary resources. Conceivably, however, courtship might have been interrupted by nightfall, and the orientation of the sleeping male ensured that courting would continue the following morning.”

Sand Flies (Lutzomyia)! For those of you fortunate enough to have worked in the Neotropics, you may well remember these relentless, miniature biting definitions of annoyance and discomfort! Well, it seems it isn’t just biologists that fall victim to torment, but unfortunately our anole friends, too!
While in the field conducting ‘Anole Patrol’ (Visual Encounter Surveys) at Kanahau Utila Research & Conservation Facility on Utila Island, Honduras, we often encounter individuals of Anolis (Norops) bicaorum tolerating ectoparasitism by Sand flies (Lutzomyia). Regretfully, we have yet to extensively research into anole ectoparasitic/host relationships, though a quick online search brings up a surprising pool of prior literature.
While my knowledge on this topic is still somewhat lacking, I figured that this little observation proves interesting and its documentation may spur a discussion of such!

An additional future threat includes the unfortunate establishment and spread of the admirably successful, yet deplorably invasive, Anolis sagrei , an adaptable, competitive and ironically ‘loathsome lizard’ previously associated with declines of native herpetofauna (a species that i am sure requires little introduction on Anole Annals!!).
