Wanted: Photographs of Flora and Fauna

We would like to challenge everyone to take photographs of fireflies and other insects in the Philippines and southeast Asia. If you can get some good images of fireflies we may publish them on this site with your credits. Send your best digital firefly photos to Terry Lynch, Naturalist.

Special Invitation

Welcome to Bagobo Woodlands. I am working to save the firefly which is becoming an endangered or threatened species in many places around the world. This involves doing basic research to document existing populations, establish their health, and develop Safe Zone plans for their preservation that our children's children may still enjoy the marvel and mystery of watching fireflies and learning about their wondrous lives.

The purpose of this project is to inspire scientists, teachers and students to study the fireflies and other insects which occur at Bagobo Woodlands, in the forest around Mt. Apo, and at other areas on Mindanao and throughout the Philippines and southeast Asia, in general.

Although a number of species of fireflies have been identified in southeast Asia, there still remains much to learn about their behavior, range, population density, and such factors as the sensitivity of populations to changes in the environment. The following challenges are proposed that a better understanding of firefly populations may be acquired that this may be used to preserve and protect existing populations.

If you have questions about fireflies please visit Firefly FAQs which is a site I produce and host. I am currently asking everyone to please send me firefly specimens preserved in 70% alcohol. See Dr. Firefly for complete instructions. You may download the form at INSECTA to use when you submit specimens for identification. If you have any questions about fireflies please contact Terry.

This spectacular image of Pteroptyx sp. glowing inside a sphere as if brought back to life from the dead, may be a premonition of the power future firefly research will bring to humanity. This is because the processes by which fireflies are able to create light and control their flash may be closely linked to the processes which bring forth life itself. Collector Garnet A. Abajero.

Firefly Experiments and Projects

Some simple observations and experiments may be made to learn more about the fireflies which occur at Bagobo Woodlands and around Mt. Apo.

  1. Firefly Activity at Bagobo Woodlands Make daily or weekly observations at Bagobo Woodlands to determine the annual occurrence of fireflies. This may involve recording the date, time, temperature, location, number of fireflies seen, flash pattern and other factors. Sightings may be reported and mapped using the Boston Museum of Science Firefly Watch criteria. It is also important that specimens observed be identified by collecting a few specimens and sending them to INSECTA. It is important to determine how many different species of fireflies are active at Bagobo Woodlands. Currently Pteroptyx sp. and Pyrocoelia sp. have been identified at Bagobo Woodlands. For this reason fireflies around the farm and orchards should be observed as well as those active along the nature trail through the gully. Keep a daily or weekly log such that over time one may be able to determine the peak periods of firefly activity. This information will help inform visitors and ecotourists to Bagobo Woodlands as to when they may expect to see fireflies and the times at which the best displays are observed.

  2. Map Mt. Apo Area Fireflies Currently it is not know how many different species of fireflies occur around the greater Mt. Apo area, either in the National Park area or near by Wildlife Refuge; nor is it known how abundant fireflies are on Mindanao or even in the Philippines, in general. Those living in the area or visiting are encouraged to more closely observe fireflies. Make logs of firefly activity and collect specimens for record and identification by sending them to INSECTA. Also join the Boston Museum of Science Firefly Watch and report firefly sightings as accurately as possible. This may also be done for other areas in southeast Asia. Information about firefly sightings is very important because as the human population in areas rapidly increases, deforestation is destroying habitats. When fireflies disappear it singles the loss of many other species. It is vital to know where fireflies occur and to make an effort to preserve and protect those areas which have healthy firefly populations. Establishing nature preserves and FIREFLY SAFE ZONES may help boost ecotourism and also serve to protect many species of flora and fauna.

The fact that there are at least two species of fireflies at Bagobo Woodlands may mean that they are in competition for territory. This represents opportunity for future research to study the nature of this competition as well as the opportunity to preserve both species of fireflies at the site.

  3. Firefly Behavior and Advanced Research at Bagobo Woodlands. The fact that there are at least two species of fireflies at Bagobo Woodlands may afford a unique opportunity for investigating firefly behavior and how these two species interact and/or compete for food and territory. Make an electronic device which is able to record the flash patters of fireflies. Determing the flash patterns of both individual and isolated male Pteroptyx sp. and Pyrocoelia sp. Then place two individuals of the same species together and record their flash patters as they come to flash in synchrony. Then place males of Pteroptyx sp. and Pyrocoelia sp. together to determine how they interact. Then determine the flash dialogue betweens males and females of both Pteroptyx sp. and Pyrocoelia sp. Once this is known place males of Pteroptyx sp. and Pyrocoelia sp. together and introduce a female, first of Pteroptyx sp. and then of Pyrocoelia sp. It will be curious to note what happens and if the males of either species are able to interfer with those of their competition. Then make small groups of males of Pteroptyx sp with one male of Pyrocoelia sp. Let the group of similar fireflies (Pteroptyx sp.) establish synchronous display. Then introduce a female first of Pteroptyx sp. and see if Pyrocoelia sp., a larger firefly, can out flash the group of Pteroptyx sp., which are smaller fireflies. Repeat this experiment introducing a female of Pyrocoelia sp. Then try the same experiment but using a group of male Pyrocoelia sp. Through such studies like this it may be possible to gain understanding of how flash behavior serves in competition for territory. Also investigate to determine if the larger male and/or female of Pyrocoelia sp. preys upon the smaller Pteroptyx sp. Is there any aggresive mimicry between these two species?

    It would also be interesting to build small flight chambers and study how the adult males of Pteroptyx sp. congergate and if the introduction of males or females of Pyrocoelia sp. may disrupt small groups of synchronous flashing male displays? Or does the establishment of groups of synchronous flashing male displays serve as a behavior which empowers the smaller Pteroptyx sp. to successifully compete for territory against the larger Pyrocoelia sp.? It may be that the smaller Pteroptyx sp. uses synchronous group flash behavior to establish dominance in this manner over the larger Pyrocoelia sp., that this is why in the gully at Bagobo Woodlands there are some high population densities of fireflies (probably Pteroptyx sp.) that have established themselves and can be seen in greatest numbers during the height of the rainy season in July or August.

    It might also be interesting to rear both Pteroptyx sp. and Pyrocoelia sp. to see how their larvae interact when offered snails, slugs or other small animals. Do the larvae of these respective species compete for food? Is one more aggressive than the other? Firefly larvae play an important role in securing a territory, especially when larvae of different species prey upon the same food source and/or are hostile or aggressive toward one another. One would need to collect various snails, slugs and other small animals to test which are the food source for the respective firefly larvae to gain some knowledge in this respect.

This dwarf firefly is known for its spactacular synchronous flashing displays which awe and delight visitors to Bagobo Woodlands. The male Pteroptyx sp. shown here was collected by Garnet A. Abajero on or about Oct. 8, 2011. Photo © 2011 by Terry Lynch.

  4. Identify Deforested Areas and Replant Trees There are many areas which have been deforested and not replanted with trees endemic to the area. It would be interesting to determine the effect of replanting trees upon rejuvenating firefly populations. The idea would be to use Bagobo Woodlands as a base-line. Once a annual log of firefly activity at Bagobo Woodlands is made, then observe for firefly activity in areas around Mt. Apo which have been impacted by over-logging or other human activity. Map forested vs. deforested areas by consulting satellite images and visiting areas to note flora and fauna which occur, including fireflies. Then replant trees endemic to the area, such as a natural variety of pine tree. Then over time observe to see how the regrowth of forest effects firefly populations which is an indicator of a health environment. This would be a long-term study which might best be done as a cooperative effort with a university and the support and sponsorship of those companies interested in management of wildlife and the forest, as through such management greatest benefit may be achieved in the long term by being able to sustain natural resources.

  5. Rearing Fireflies Rearing fireflies is a challenging and rewarding experience. This would involve collecting fertile females of known species and allowing them to lay eggs; then feeding the tiny larvae which emerge their host food (snails) until they grow and pupate. The adults which then emerge could be mated to rear even more fireflies. Over time one might be able to establish a healthy breeding population of fireflies that could be used in a variety of ways. This might include repopulating areas that were deforested. It might also include creating very impressive enclosed firefly gardens or insectaries where large displays of fireflies may be seen. Also by being able to rear and maintain various species of fireflies one will have stock to use for research and study without impacting populations that occur in the wild.

    Although among the most tiny fireflies in the world, Pteroptyx sp. is a magistic firefly when it comes to its synchronous flashing displays. Pteroptyx sp. occurs in abundance at Bagobo Woodlands and is probably the species responsible for large synchronous displays seen during the rainy season. The specimen shown here at 20X is preserved in 70% alcohol and was collected by Garnet A. Abajero on or about Oct. 8, 2011. Photo © 2011 by Terry Lynch.

  6. Photographing Fireflies There are many types of photographs of fireflies which present a challenge. This includes making videos of fireflies. Try to photograph fireflies in flight or flashing in synchrony. Make close-up macro photographs of fireflies exhibiting such behavior as mating or laying eggs. Photograph firefly larvae feeding upon snails or other small animals. Can you discover if area fireflies eat earthworms or other small, soft bodies animals other than snails and prove this by making a video of feeding behavior of firefly larvae? Photographs may be of aid in determining the genus-species of the host food of fireflies. Photograph fireflies in their natural habitat flashing upon leaves or other vegetation as well as feeding upon soft bodied animals. Try to make very close-up videos of fireflies flashing, mating, feeding, and laying eggs. Put a firefly upon a clean, clear plate of glass or microscope slide and take close-up photographs or videos as it flashes, that one may see the reflected image of the firefly's lantern. Try to make a video of male and female fireflies flashing in close proximity, and then coming together to mate. Note: Flash photography at night of fireflies in the gully area of Bagobo Woodlands is not permitted. However, you may photograph or make videos of fireflies without a flash; such low-light level photography or videography is a challenge but can produce some very interesting results.
