Family Gomphidae

Ictinogomphus ferox COMMON TIGERTAIL

Identification

Very Large

Length up to 95mm; Wingspan attains 101mm.

This is the largest member of the family Gomphidae in the region.

Both sexes are readily identifiable by their very large size, large black foliations near the abdomen tip and bold black and yellow colouration.

Most similar to Gomphidia quarrei (Southern Fingertail) but that species is smaller, more slender and lacks the large foliations on the abdomen.

Habitat

Inhabits the margins of rivers, lakes, pans, marshes and dams. Mostly confined to the warmer savanna regions. It can be found at both still and flowing water and prefers areas that are lined with tall grasses, sedges and especially Phragmites reeds. This is the only large Gomphid in South Africa that commonly inhabits the fringes of large still-water habitats.

Behaviour

Conspicuous as it sits prominently in the open on reeds or other similar perches. The Common Tigertail hunts from a perch. They return to their post after each foray to chase down prey or a potential rival. The flight is swift and powerful. They often skypoint during the heat of the day to reduce the amount of the body in direct sunlight. Females and non-breeding males are mostly found further from the water.

Status and Conservation

Ictinogomphus ferox is common in the northern and eastern parts of South Africa. Vagrants may occasionally be found in other parts of the country. It is listed as of Least Concern in the IUCN Red List of Threatened Species. The Common Tigertail is fairly tolerant of habitat degradation. It occurs commonly at man-made dams and reservoirs, provided they offer suitable habitat.

Distribution

Found almost throughout sub-Saharan Africa, although it appears to be less common in West Africa. In South Africa it is mostly confined to the North and North-East.

Below is a map showing the distribution of records for Common Tigertail in the OdonataMAP database as at February 2020.

The next map below is an imputed map, produced by an interpolation algorithm, which attempts to generate a full distribution map from the partial information in the map above. This map will be improved by the submission of records to the OdonataMAP section of the Virtual Museum.

Ultimately, we will produce a series of maps for all the odonata species in the region. The current algorithm is a new algorithm. The objective is mainly to produce “smoothed” maps that could go into a field guide for odonata. This basic version of the algorithm (as mapped above) does not make use of “explanatory variables” (e.g. altitude, terrain roughness, presence of freshwater — we will be producing maps that take these variables into account soon). Currently, it only makes use of the OdonataMAP records for the species being mapped, as well as all the other records of all other species. The basic maps are “optimistic” and will generally show ranges to be larger than what they probably are.

These maps use the data in the OdonataMAP section of the Virtual Museum, and also the database assembled by the previous JRS funded project, which was led by Professor Michael Samways and Dr KD Dijkstra.
